DECISION
PER CURIAM:
1 1 V.M. (Mother) appeals the termination of her parental rights. Mother does not challenge the juvenile courts determination that grounds for termination exist. Her only challenge on appeal is to the juvenile courts decision that it was in C.C.s best interest to terminate Mothers parental rights and allow C.C. to be adopted. We affirm.
T2 Mother argued in the juvenile court that one-year-old C.C. should be placed in permanent custody and guardianship, rather than being adopted, and that Mother should retain the right to visit or contact C.C. Because Mother does not argue that she should regain custody, nor does she dispute the juvenile courts determination that the State had proven several grounds for termination, we review only the decision that termination of the parents rights is in the best interests of the child. In re A.C.M., 2009 UT 30, ¶ 23, 221 P.3d 185 (stating that after the court finds that grounds for termination exist, the court must determine whether termination of parental rights is in the childs best interests). Because of the factually intense nature of such an inquiry, the juvenile courts decision should be afforded a high degree of deference. In re B.R., 2007 UT 82, ¶ 12, 171 P.3d 435. Thus, in order to overturn the juvenile courts decision, the result must be against the clear weight of the evidence or leave the appellate court with a firm and definite conviction that a mistake has been made. Id. (internal quotation marks and citation omitted). When a foundation for the courts decision exists in the evidence, an appellate court may not engage in a reweighing of the evidence. Id.
T3 Although Mother exhibited good or excellent parenting skills in supervised settings, her habitual and continuous use of controlled substances interfered with her ability to be a parent to C.C. He was removed from Mothers custody when he was just two months old, and he has resided for most of his young life in the same legal risk foster home. The juvenile court found that the foster home was a stable, loving home where C.C. was doing well and his needs were being met. The foster parents wished to adopt C.C. In contrast, a five-week trial home placement with Mother ended unsue-cessfully when Mother relapsed and was discharged from her residential substance abuse treatment program. Mother does not seek to regain custody of C.C., but she does seek to retain parental rights, which would prevent C.C. from being adopted. After receiving notice of the date of trial, Mother elected not to attend the termination trial either in person or by telephone. The juvenile courts decision that the termination of Mothers parental rights was in C.C.s best interest is amply supported by the evidence presented to the juvenile court.
T 4 Because a foundation exists in the record for the juvenile courts determination that it would be in the best interest of C.C. to terminate Mothers parental rights and allow him to be adopted, we affirm the decision to terminate Mothers parental rights.
