Under Nebraska law, terminating parental rights requires both clear and convincing evidence that one of the statutory grounds enumerated in § 43-292 exists and clear and convincing evidence that termination is in the best interests of the children. In re Interest of Jay'Oni W. et al., 31 Neb.App. 302, 979 N.W.2d 290 (2022). Clear and convincing evidence is that amount of evidence which produces in the trier of fact a firm belief or conviction about the existences of a fact to be proven.

Children cannot, and should not, be suspended in foster care or be made to await uncertain parental maturity. In re Interest of Jay'Oni W. et al., 31 Neb.App. 302, 979 N.W.2d 290 (2022). We conclude that the State showed by clear and convincing evidence that Matthew Sr. was unfit, and that termination of his parental rights was in the children's best interests.

Children cannot, and should not, be suspended in foster care or be made to await uncertain parental maturity. In re Interest of Jay'Oni W. et al., 31 Neb.App. 302, 979 N.W.2d 290 (2022). We conclude that the State showed by clear and convincing evidence that Kylee and Juellian were unfit, and that termination of their parental rights was in their children's best interests.

When a parent is unable or unwilling to rehabilitate himself or herself within a reasonable period of time, the child's best interests require termination of parental rights. In re Interest of Jay'Oni W. et al., 31 Neb.App. 302, 979 N.W.2d 290 (2022). The 15-month condition contained in § 43-292(7) provides a reasonable timetable for parents to rehabilitate themselves.
