I am the custodial parent and my 7 year old daughter's biological father and his wife live in a motel. I found out when my daughter came home from the last visit that she had to sleep with her dad and his wife. Is that even legal? Does he have to at least buy an air mattress for my daughter for her to use when she is there? She is about to have to go and stay a month with him for summer visitation and I am wondering what has to change if anything??
