¶ 1. This case presents two issues.1 First, we must decide whether as a condition of *452probation, a father of nine children, who has intentionally refused to pay child support, can be required to avoid having another child, unless he shows that he can support that child and his current children. We conclude that in light of Oakley's ongoing victimization of his nine children and extraordinarily troubling record manifesting his disregard for the law, this anomalous condition — imposed on a convicted felon facing the far more restrictive and punitive sanction of prison — is not overly broad and is reasonably related to Oakley's rehabilitation. Simply put, because Oakley was convicted of intentionally refusing to pay child support — a felony in Wisconsin — and could have been imprisoned for six years, which would have eliminated his right to procreate altogether during those six years, this probation condition, which infringes on his right to procreate during his term of probation, is not invalid under these facts. Accordingly, we hold that the circuit court did not erroneously exercise its discretion.
¶ 2. Second, we must decide whether an individual waives his or her claim of error that the State was impermissibly allowed to withdraw from an earlier plea agreement by entering into a subsequent plea agreement. When a defendant pleads no contest, he or she waives all defenses based on a denial of due process because the prosecutor breached an earlier plea agreement. Thus, we find that there was waiver here.

¶ 3. David Oakley (Oakley), the petitioner, was initially charged with intentionally refusing to pay child support for his nine children he has fathered with *453four different women. The State subsequently charged Oakley with seven counts of intentionally refusing to provide child support as a repeat offender. His repeat offender status stemmed from intimidating two witnesses in a child abuse case — where one of the victims was his own child. State v. Oakley, 226 Wis. 2d 437, 441, 594 N.W.2d 827 (Ct. App. 1999), rev'd on other grounds, State v. Oakley, 2000 WI 37, 234 Wis. 2d 528, 609 N.W.2d 786. Oakley and the State entered into a plea agreement on the seven counts, but the State, after learning that Oakley's probation in Sheboygan County was in the process of being revoked, moved at sentencing to withdraw the plea agreement^ The circuit court for Manitowoc County, Fred H. Hazlewood, Judge, granted the State's motion.
¶ 4. Oakley then entered into another plea agreement in which he agreed to enter a no contest plea to three counts of intentionally refusing to support his children and have the other four counts read-in for sentencing. He further agreed that he would not complain on appeal about the State's withdrawal from the first plea agreement. The State, in turn, agreed that in exchange for his no contest plea, it would cap its sentencing recommendation to a total of six years on all counts. Oakley, however, was free to argue for a different sentence.
¶ 5. At sentencing, Judge Hazlewood informed Oakley that by pleading no contest, he waived his right to have the State prove that he was legally obligated to support his children and that he intentionally refused to do so for at least 120 days contrary to Wis. Stat. § 948.22(2) (1997-98).2 The State noted that during the relevant time period, Oakley had paid no child sup*454port and that there were arrears in excess of $25,000. Highlighting Oakley's consistent and willful disregard for the law and his obligations to his children, the State argued that Oakley should be sentenced to six years in prison consecutive to his three-year sentence in She-boygan County.3 Oakley, in turn, asked for the opportunity to maintain full-time employment, provide for his children, and make serious payment towards his arrears.
¶ 6. After taking into account Oakley's ability to work and his consistent disregard of the law and his obligations to his children, Judge Hazlewood observed that "if Mr. Oakley had paid something, had made an earnest effort to pay anything within his remote ability to pay, we wouldn't be sitting here," nor would the State argue for six years in prison. But Judge Hazle-wood also recognized that "if Mr. Oakley goes to prison, he's not going to be in a position to pay any meaningful support for these children." Therefore, even though Judge Hazlewood acknowledged that Oakley's "defaults, are obvious, consistent, and inexcusable," he decided against sentencing Oakley to six years in prison consecutive to his three-year sentence in She-boygan County, as the State had advocated. Instead, Judge Hazlewood sentenced Oakley to three years in prison on the first count, imposed and stayed an eight-year term on the two other counts, and imposed a five-year term of probation consecutive to his incarceration. Judge Hazlewood then imposed the condition at issue here: while on probation, Oakley cannot have any more children unless he demonstrates that he had the ability to support them and that he is supporting the children *455he already had. After sentencing, Oakley filed for post-conviction relief contesting this condition and the State's withdrawal from the first plea agreement.
¶ 7. In a per curiam opinion, the court of appeals affirmed the circuit court's rulings on both issues. State v. Oakley, No. 99-3328-CR, unpublished slip op. at ¶ 1 (Wis. Ct. App. Sept. 13, 2000). The court of appeals found that the condition placed on Oakley was not overly broad and that it was reasonable. The court also found that Oakley's decision to enter into the subsequent plea agreement "waived his right to challenge matters relating to the first plea agreement." Id. at ¶ 5. Oakley petitioned this court for review, which we granted.
II
¶ 8. Oakley challenges the constitutionality of a condition of his probation for refusing to pay child support. The constitutionality of a condition of probation raises a question of law, which this court reviews independently without deference to the decisions of the circuit court or the court of appeals. See State v. Griffin, 131 Wis. 2d 41, 49, 388 N.W.2d 535 (1986); Edwards v. State, 74 Wis. 2d 79, 85, 246 N.W.2d 109 (1976).
¶ 9. Refusal to pay child support by so-called "deadbeat parents" has fostered a crisis with devastating implications for our children.4 Of those single parent households with established child support awards or orders, approximately one-third did not receive any payment while another one-third received *456only partial payment.5 For example, in 1997, out of $26,400,000,000 awarded by a court order to custodial mothers, only $15,800,000,000 was actually paid, amounting to a deficit of $10,600,000,000.6 These figures represent only a portion of the child support obligations that could be collected if every custodial parent had a support order established.7 Single mothers disproportionately bear the burden of nonpayment as the custodial parent.8 On top of the stress of being a single parent, the nonpayment of child support frequently presses single mothers below the poverty line.9 In fact, 32.1% of custodial mothers were below the poverty line in 1997, in comparison to only 10.7% of custodial fathers.10 Indeed, the payment of child support is widely regarded as an indispensable step in assisting single mothers to scale out of poverty, espe*457cially when their welfare benefits have been terminated due to new time limits.11
¶ 10. The effects of the nonpayment of child support on our children are particularly troubling. In addition to engendering long-term consequences such as poor health, behavioral problems, delinquency and low educational attainment, inadequate child support is a direct contributor to childhood poverty.12 And childhood poverty is all too pervasive in our society. Over 12 million or about one out of every six children in our country lives in poverty.13 In Wisconsin, poverty strikes approximately 200,000 of our children with 437,000 at or below 200% of the poverty level in 1999.14 Although payment of child support alone may not end childhood poverty, it could reduce current levels and raise childhood standards of living.15 Child support — when paid — on average amounts to over one-quarter of a poor child's family income.16 There is little doubt that the payment of child support benefits pov*458erty-stricken children the most.17 Enforcing child support orders thus has surfaced as a major policy directive in our society.
¶ 11. In view of the suffering children must endure when their noncustodial parent intentionally refuses to pay child support, it is not surprising that the legislature has attached severe sanctions to this crime.18 Wis. Stat. § 948.22(2). This statute makes it a Class E felony for any person "who intentionally fails for 120 or more consecutive days to provide spousal, grandchild or child support which the person knows or reasonably should know the person is legally obligated to provide... ."19 A Class E felony is punishable with "a *459fine not to exceed $10,000 or imprisonment not to exceed 2 years, or both." Wis. Stat. § 939.50(3)(e). The legislature has amended this statute so that intentionally refusing to pay child support is now punishable by up to five years in prison. See Wis. Stat. § 939.50(3)(e)(1999-2000).
¶ 12. But Wisconsin law is not so rigid as to mandate the severe sanction of incarceration as the only means of addressing a violation of § 948.22(2). In sentencing, a Wisconsin judge can take into account a broad array of factors, including the gravity of the offense and need for protection of the public and potential victims. State v. Guzman, 166 Wis. 2d 577, 592, 480 N.W.2d 446 (1992). Other factors — concerning the convicted individual — that a judge can consider include:
the past record of criminal offenses; any history of undesirable behavior patterns; the defendant's personality, character and social traits; the results of a presentence investigation; the vicious or aggravated nature of the crime; the degree of defendant's culpability; the defendant's demeanor at trial; the defendant's age, educational background and employment record; the defendant's remorse, repentance and cooperativeness; the defendant's need for close rehabilitative control; the rights of public; and the length of pretrial detention.
Id. After considering all these factors, a judge may decide to forgo the severe punitive sanction of incarceration and address the violation with the less restrictive alternative of probation coupled with specific conditions. Wisconsin Stat. § 973.09(l)(a) provides:
[I]f a person is convicted of a crime, the court, by order, may withhold sentence or impose sentence *460under s. 973.15 and stay its execution, and in either case place the person on probation to the department for a stated period, stating in the order the reasons therefor. The court may impose any conditions which appear to be reasonable and appropriate.
The statute, then, grants a circuit court judge broad discretion in fashioning a convicted individual's conditions of probation. As we have previously observed, "[t]he theory of the probation statute is to rehabilitate the defendant and protect society without placing the defendant in prison. To accomplish this theory, the circuit court is empowered by Wis. Stat. § 973.09(l)(a) to fashion the terms of probation to meet the rehabilitative needs of the defendant." State v. Gray, 225 Wis. 2d 39, 68, 590 N.W.2d 918 (1999). While rehabilitation is the goal of probation, judges must also concern themselves with the imperative of protecting society and potential victims. On this score, we have explained:
The theory of probation contemplates that a person convicted of a crime who is responsive to supervision and guidance may be rehabilitated without placing him in prison. This involves a prediction by the sentencing court society will not be endangered by the convicted person not being incarcerated. This is risk that the legislature has empowered the courts to take in the exercise of their discretion.. ..
If the convicted criminal is thus to escape the more severe punishment of imprisonment for his wrongdoing, society and the potential victims of his anti-social tendencies must be protected.
State v. Evans, 77 Wis. 2d 225, 231, 252 N.W.2d 664 (1977). Thus, when a judge allows a convicted individual to escape a prison sentence and enjoy the relative *461freedom of probation, he or she must take reasonable judicial measures to protect society and potential victims from future wrongdoing. To that end — along with the goal of rehabilitation — the legislature has seen fit to grant circuit court judges broad discretion in setting the terms of probation.
¶ 13. Nevertheless, this broad discretion given to trial judges has come under fire by various commentators, especially where trial judges elsewhere in the country have imposed probation conditions that reflect their own idiosyncrasies rather than serve a rehabilitative purpose.20 We agree that judges should not abuse their discretion by imposing probation conditions on convicted individuals that reflect only their own idiosyncrasies. Instead, they should use their discretion in setting probation conditions to further the objective of rehabilitation and protect society and potential victims from future wrongdoing. And because we recognize that convicted felons may have trouble conforming their future conduct to the law, we uphold the power of a judge to tailor individualized probation conditions per Wis. Stat. § 973.09(l)(a).
¶ 14. In the present case, the record indicates that Judge Hazlewood was familiar with Oakley's *462abysmal history prior to sentencing. The record reveals that Judge Hazlewood knew that Oakley had a number of support orders entered for his nine children, but he nevertheless continually refused to support them. He was aware that Oakley's probation for intimidating two witnesses in a child abuse case — where one of the witnesses was his own child and the victim — was in the process of being revoked. Judge Hazlewood was also apprised that Oakley had promised in the past to support his children, but those promises had failed to translate into the needed support. Moreover, he knew that Oakley had been employed and had no impediment preventing him from working. As the court of appeals observed in the witness intimidation case against Oakley, "[t]he refusal to pay the fines and the victim intimidation both show Oakley's cavalier attitude toward the justice system. . . .Oakley needs to be rehabilitated from his perception that one may flout valid court orders and the judicial process with impunity and suffer no real consequence." Oakley, 226 Wis. 2d at 441. Given his knowledge of Oakley's past conduct, Judge Hazlewood was prepared to fashion a sentence that would address Oakley's ongoing refusal to face his obligations to his nine children as required by law.
¶ 15. In doing so, Judge Hazlewood asserted that some prison, time coupled with conditional probation might convince Oakley to stop victimizing his children. With probation, Judge Hazlewood sought to rehabilitate Oakley while protecting society and potential victims — Oakley's own children — from future wrongdoing.21 The conditions were designed to assist Oakley *463in conforming his conduct to the law. In Wisconsin, as expressed in Wis. Stat. § 948.22(2), we have condemned unequivocally intentional refusal to pay child support and allow for the severe sanction of prison to be imposed on offenders. Here, the judge fashioned a condition that was tailored to that particular crime, but avoided the more severe punitive alternative of the full statutory prison term through the rehabilitative tool of probation. At the same time, Judge Hazlewood sought to protect the victims of Oakley's crimes — Oakley's nine children.
¶ 16. But Oakley argues that the condition imposed by Judge Hazlewood violates his constitutional right to procreate.22 This court, in accord with *464the United States Supreme Court, has previously recognized the fundamental liberty interest of a citizen to choose whether or not to procreate. Eberhardy v. Circuit Court for Wood County, 102 Wis. 2d 539, 561, 307 N.W.2d 881 (1981); Skinner v. Oklahoma ex rel. Williamson, 316 U.S. 535, 541 (1942) (recognizing the right to procreate as "one of the basic civil rights of man"). Accordingly, Oakley argues that the condition here warrants strict scrutiny.23 That is, it must be *465narrowly tailored to serve a compelling state interest. See Zablocki v. Redhail, 434 U.S. 374, 388 (1978). Although Oakley concedes, as he must, that the State's interest in requiring parents to support their children is compelling, he argues that the means employed here is not narrowly tailored to serve that compelling interest because Oakley's "right to procreate is not restricted but in fact eliminated." According to Oakley, his right to procreate is eliminated because he "probably never will have the ability to support" his children. Therefore, if he exercises his fundamental right to procreate while on probation, his probation will be revoked and he will face the stayed term of eight years in prison.
*466¶ 17. While Oakley's argument might well carry the day if he had not intentionally refused to pay child support, it is well-established that convicted individuals do not enjoy the same degree of liberty as citizens who have not violated the law. See Evans, 77 Wis. 2d at 230 (asserting that "liberty enjoyed by a probationer is, under any view, a conditional liberty" and that probationer's "position is not that of a non-convicted citizen”); Von Arx v. Schwarz, 185 Wis. 2d 645, 658, 517 N.W.2d 540 (Ct. App. 1994) (observing that felon on probation does not enjoy the same constitutional guarantees as the citizenry). We emphatically reject the novel idea that Oakley, who was convicted of intentionally failing to pay child support, has an absolute right to refuse to support his current nine children and any future children that he procreates, thereby adding more child victims to the list. In an analogous case, Oregon upheld a similar probation condition to protect child victims from their father's abusive behavior in State v. Kline, 963 P.2d 697, 699 (Or. Ct. App. 1998).24 *467In Kline, the defendant physically and emotionally abused his wife and children, especially when high on methamphetamine, which caused him to become angry and hostile. Id. at 698. Until his parental rights to his son were terminated, he abused him regularly, eventually breaking his arm. Id. Subsequently, he and his wife had a baby girl. Id. Undeterred, the defendant spiral fractured his two-and-a-half month old baby girl's leg and bruised her head and chest, causing her to scream uncontrollably. Id. He admitted that" 'I caused the bruises on the baby because I don't know my own strength'" and explained his conduct with the observation that" 'babies are so hard to understand. They are so frustrating.'" Id. at 699. The defendant was convicted of criminal mistreatment and as a condition of his probation he was required to successfully complete drug and anger management program and obtain prior written approval of the court before fathering any future child. Id. at 699. The defendant contested the condition as violating his fundamental right to procreate and asserted that strict scrutiny applied.
¶ 18. The court rejected the defendant's argument that strict scrutiny applied to the probation condition at issue. Securing the rights of his child victims, the court wrote that "[t]he condition provides potential victims with protection from future injury and interferes with defendant's fundamental rights to a permissible degree." Id. The court acknowledged that *468the trial court — like the circuit court in the present case — "did not impose a total ban on defendant's reproductive rights." Id. The Kline court further noted that the trial court "expressed its concern for the safety of any children defendant might conceive in the future in the light of defendant's potential for violence associated with his anger and drug abuse problems." Id. Similarly, we believe that in light of Oakley's troubling record of child witness intimidation and intentional refusal to pay child support, denying his nine children assistance for their basic needs, the condition here will provide his child victims and any future child victims with some measure of protection from any of Oakley's future acts that may violate the law.
¶ 19. Furthermore, Oakley fails to note that incarceration, by its very nature, deprives a convicted individual of the fundamental right to be free from physical restraint, which in turn encompasses and restricts other fundamental rights, such as the right to procreate.25 See Meyer v. Nebraska, 262 U.S. 390, 399 (1923) (acknowledging that liberty defined by the Four*469teenth Amendment denotes more than just freedom from bodily restraint); State ex rel. Anderson-El v. Cooke, 2000 WI 40, ¶ 24, 234 Wis. 2d 626, 610 N.W.2d 821 (noting that a prisoner's rights and privileges are diminished compared to other citizens, although a prisoner must still be afforded certain constitutional protections). Therefore, given that a convicted felon does not stand in the same position as someone who has not been convicted of a crime26 , we have previously stated that "conditions of probation may impinge upon constitutional rights as long as they are not overly broad and are reasonably related to the person's rehabilitation." Edwards v. State, 74 Wis. 2d 79, 84-85, 246 N.W.2d 109 (1976).27 In State v. Krebs, 212 Wis. 2d 127, *470130-31, 568 N.W.2d 26 (Ct. App. 1997), the court of appeals recently applied this established standard to *471uphold a condition of probation that required a defendant who sexually assaulted his own daughter to *472obtain his probation agent's approval before entering into an intimate or sexual relationship. The court *473found that although the condition infringed upon a constitutional right, it was reasonable and not overly broad. Id. at 131.
¶ 20. Applying the relevant standard here, we find that the condition is not overly broad because it does not eliminate Oakley's ability to exercise his constitutional right to procreate. He can satisfy the condition of probation by making efforts to support his children as required by law. Judge Hazlewood placed no limit on the number of children Oakley could have. Instead, the requirement is that Oakley acknowledge the requirements of the law and support his present and any future children.28 If Oakley decides to continue his present course of conduct — intentionally refusing to pay child support — he will face eight years in prison regardless of how many children he has. Furthermore, this condition will expire at the end of his *474term of probation. He may then decide to have more children, but of course, if he continues to intentionally refuse to support his children, the State could charge him again under § 948.22(2). Rather, because Oakley can satisfy this condition by not intentionally refusing to support his current nine children and any future children as required by the law, we find that the condition is narrowly tailored to serve the State's compelling interest of having parents support their children.29 It is also narrowly tailored to serve the State's compelling interest in rehabilitating Oakley through probation rather than prison. The alternative to probation with conditions — incarceration for eight years — would have further victimized his children.30 And it is undoubtedly *475much broader than this conditional impingement on his procreative freedom for it would deprive him of his fundamental right to he free from physical restraint. Simply stated, Judge Hazlewood preserved much of Oakley's liberty by imposing probation with conditions rather than the more punitive option of imprisonment. See State v. Evans, 77 Wis. 2d 225, 230, 252 N.W.2d 664 (1977) ("Whether sentence 'is withheld or imposed and stayed, a convicted person's status as a probationer is a matter of grace or privilege and not a right' made possible by the legislature.") (citation omitted).
¶ 21. Moreover, the condition is reasonably related to the goal of rehabilitation. A condition is reasonably related to the goal of rehabilitation if it assists the convicted individual in conforming his or her conduct to the law. See State v. Miller, 175 Wis. 2d 204, 210, 499 N.W.2d 215 (Ct. App. 1993) (ruling that condition on probationer convicted of making obscene telephone calls forbidding him to make calls to any woman other than a family member was reasonably related to his rehabilitation); Edwards, 74 Wis. 2d at 85 (holding that condition on probationer convicted of three crimes with co-defendants banning her from having any contact with her co-defendants was reasonably related to her rehabilitation). Here, Oakley was convicted of intentionally refusing to support his children. The condition at bar will prevent him from adding victims if he continues to intentionally refuse to support his children. As the State argues, the condition essentially bans Oakley from violating the law again. Future violations of the law would be detrimental to Oakley's rehabilitation, which necessitates preventing him from *476continuing to disregard its dictates. Accordingly, this condition is reasonably related to his rehabilitation because it will assist Oakley in conforming his conduct to the law.
I — I HH 1 — 1
¶ 22. Having determined that the probation condition is valid, we turn now to the issue of whether Oakley waived his claim of error that the State was impermissibly allowed to withdraw from an earlier plea agreement by entering into a subsequent plea agreement with the State.31 Whether a defendant has waived his or her claim of error by entering a plea is a question of law which this court reviews de novo. State v. Lechner, 217 Wis. 2d 392, 404 n.8, 576 N.W.2d 912 (1998); State v. Riekkoff, 122 Wis. 2d 119, 122-25, 332 N.W.2d 744 (1983).
¶ 23. As this court has previously stated, "[i]t is well-established that a plea of no contest, knowingly and understanding^ made, constitutes a waiver of non-jurisdictional defects and defenses, including claimed violations of constitutional rights." Lechner, 217 Wis. 2d at 404 n.8. Therefore, when a defendant *477pleads no contest, he or she waives all defenses based on a denial of due process because the prosecutor breached an earlier plea agreement. In the instant case, Oakley pled no contest based on his second plea agreement. By doing so, he waived any claim of error that may have occurred when the circuit court permitted the State to withdraw from the first plea agreement.32 As the court of appeals noted in State v. Paske, 121 Wis. 2d 471, 474, 360 N.W.2d 695 (Ct. App. 1984), "[i]t is only when the consensual character of the plea is called into question that the validity of a guilty plea may be impaired." There is no indication here that Oakley's plea was nonconsensual. Accordingly, we find that Oakley, by pleading no contest to the second plea agreement, waived his claim of error that the State was impermissibly allowed to withdraw from the earlier plea agreement.
IV
¶ 24. In conclusion, based on the atypical facts presented by this case, the Constitution does not shield Oakley — whose record evidences consistent disregard for the law and ongoing victimization of his own nine children — from this unique probation condition where *478he has intentionally refused to support his children. Under the exceptional factors presented by this case, the probation condition is not overbroad and it is reasonably related to the probationary goal of rehabilitation. Indeed, this condition is narrowly tailored to serve the compelling state interest of requiring parents to support their children as well as rehabilitating those convicted of crimes. Moreover, this condition will assist Oakley in conforming his conduct to the law and is therefore reasonably related to his rehabilitation. Finally, we find that he waived any claim of error by pleading no contest under the second plea agreement.
By the Court. — The decision of the court of appeals is affirmed.
