My step daughter is 10. My husband and the child's mother have had shared custody since the child was 4 months old. Today she told her mother that she wants to spend more time with her, live with her a few more times a week. She spends a week there and a week with her father. We only live 5 blocks from one another in a small community. I do not think that this is a decision for her to make. Can anyone help, Please.
