In RE: Zaylen R.

This appeal involves a dispute over the custody of a non-marital child. The child's father requested the Wilson County Juvenile Court to designate him as the child's primary residential parent because of the mother's history of substance abuse. Following a bench trial, the juvenile court designated the mother as the child's primary residential parent and established a visitation schedule for the father. The court also ordered the father to pay child support and to maintain insurance for the child. The father asserts on this appeal (1) that the juvenile court's findings of fact were insufficient, (2) that the evidence does not support designating the mother as the child's primary residential parent, and (3) that the court based its decision on the outmoded tender years doctrine. We affirm the juvenile court's order.
