DANILSON, J.

A mother appeals the termination of her parental rights to her four children.1 Notwithstanding five years of services and nineteen months of out-of-home placement, the children are unable to return to their mother's care as the mother is unable to provide a safe home. We affirm.

The mother complains of five evidentiary rulings of the juvenile court. However, she cites no authority to support her claim that the rulings were in error—we therefore find these issues waived. See Iowa R. App. P. 6.1401— Form 5 (providing form for appeal in termination of parental rights cases and requiring "supporting legal authority" for each issue); see also Iowa R. App. P. 6.903(2)(g)(3) ("Failure to cite authority in support of an issue may be deemed waiver of that issue.").

All of the children are over four years of age, have been adjudicated children in need of assistance, have been out of the mother's custody for at least nineteen months, and cannot be returned to the mother's custody at the present time. The juvenile court has outlined in detail the five-year history of the mother's involvement with services designed to correct the mother's inability to provide a safe, secure, and stable home for these children. As succinctly summarized by the juvenile court:

Nothing is to be gained by our reiteration of that history or of the mother's continuing parental deficits. Upon our de novo review, see In re A.B., 815 N.W.2d 764, 773 (Iowa 2012), we find there is clear and convincing evidence supporting the termination of the mother's parental rights pursuant to Iowa Code section 232.116(1)(f) (2013).2

We also find termination will best provide for the children's "long-term nurturing and growth . . ., and to the physical, mental, and emotional condition and needs of the child[ren]." A.B., 815 N.W.2d at 776 (noting that after finding statutory grounds for termination, court must also determine whether termination is in children's best interests pursuant to Iowa Code § 232.116(2)). The therapist for the oldest two children noted that they have an "overwhelming need for permanency" and recommended termination of parental rights. A.B. has special needs and "has suffered the most significant behavioral changes since increasing visitation" with his parents. The mother contends the youngest, R.B., has no behavior issues and thus can be returned to her. But the juvenile court opined that R.B.'s lack of behavioral issues was due to the child's lack of time in her parents' care: "Having spent the least amount of time of all the children with their parents, she seems to be the most well-adjusted." The juvenile court found—and we concur—"The children are suffering emotionally from the uncertainty in their lives and their parents' shortcomings. It is in the children's best interest that termination occur."

We also reject the mother's contention that there is a close parent-child relationship that might preclude termination. See Iowa Code § 232.116(3)(c). The record does not support a finding of a bond such that termination would be detrimental to the children. The foster mother testified, "I can honestly say I don't think they [the children] care one way or the other. It's kind of gotten to that. She's here. She's not here. They don't tend to be bothered if she's not. But they don't ask if she's coming."

We affirm the termination of the mother's parental rights to M.B., T.B., A.B. and R.B.

AFFIRMED.
