Since your daughter spends more then 50% of the time with the mother then she can get child support for her. I'd say she probably took on the insurance so she can show that she is paying out more money then you are. Who keeps your daughter when you work during the summer time she spends with you. If it is your girlfriend or mother is helping in the summer time then there would be no reason that a judge would rule against you doing the same on your weekends. It sounds like you need to go to mediation and get the wording changed so other family members can also spend time with your daughter when you can't. It is only fair that the child builds a close relationship with your girlfriend of 3 years or your mother.
