If said child is 13 or under, the visitation IS forced, or will be when there is a custody agreement.
What do YOU think is said child's objection to the visitation? Do they just want to sleep in their own bed? Do they miss their friends in the neighborhood when they're gone? Do they not like H's living quarters? Are they mad at dad and don't want to see him? Is it something about dad's behavior when they're there that disturbs them?
