ship.” Based on the record, we conclude that the trial court’s finding that it was in E.S.’ best interests to award custody to Everett was not an abuse of discretion.
B. Trial Court’s Jurisdiction Over R.S.
Respondent next argues that the trial court lacked jurisdiction over R.S. because his father never received notice of the petition or any of the proceedings. Specifically, respondent contends that R.S. was born during respondent’s marriage to Michael Walker. As such, respondent contends that Michael is presumed to be the father of R.S. pursuant to section 5 of the Illinois Parentage Act of 1984 (Parentage Act) (750 ILCS 45/5 (West 2000)). The State argues, though, that this presumption may be rebutted or, alternatively, respondent should be estopped from raising the argument because it is wholly inconsistent with the position she took in the trial court. We agree with the State.
•5 In juvenile proceedings, due process requires adequate notice of the proceedings to a minor and his parents. In re B.L., 315 Ill. App. 3d 602, 605, 734 N.E.2d 476, 478 (2000). A pleading in a juvenile proceeding that fails to name and notify the necessary respondents fails to invoke the jurisdiction of the court and thereby renders its orders void. B.L., 315 Ill. App. 3d at 605, 734 N.E.2d at 478. The matter is forfeited, however, and diligence on the part of the State may be assumed, unless some question is raised in the circuit court regarding the failure to identify or locate a noncustodial parent whose identity or address is unknown to the State at the outset of the proceedings. B.L., 315 Ill. App. 3d at 605, 734 N.E.2d at 478.
•6 Here, the State’s petition listed respondent and Everett as the parents of both minors. The State amended the petition by interlineation, to reflect that Everett was the father of E.S. only. After respondent’s attorney represented to the court that R.S. was conceived by artificial insemination and had no father, the State requested the petition be amended to show R.S.’ father to be unknown. In January 2000, the State filed an amended petition listing R.S.’ father as “unknown.”
Initially, we note that the record does not indicate that the State published notice as to any unknown father. While the statute requires publication of notice as to all to whom it may concern (705 ILCS 405/ 2 — 16 (West 2000)), the statute does not address any notice requirement when an unknown, i.e., anonymous, sperm donor is involved. We conclude, however, that no notice is required to be given to an anonymous sperm donor. Our determination is supported by section 3 of the Parentage Act (750 ILCS 40/3 (West 2000)). Specifically, section 3(b) of the Parentage Act provides:
