According to op, the order says that she has the child on Thursday and Friday once he is school age. She currently doesn't have the child at all during the week. Neither time share says mom is or will be custodial parent. So unless she gets that changed, all of this talk about child support is moot. Not sure why it became such a focus anyway, except that money and making sure dad takes as much of the burden of caring for the kid as possible seem to be ops biggest concerns.
According to mom, dad thinks mom should have to take Thursday and Friday since the child is now "in school" and mom thinks dad is trying to shirk his responsibilities and should still have to keep the child on those days since "school age" is 5 in her understanding of Texas law.
Neither parent actually wants the kid on those days. "You should file for child support" seems like the last thing I'd think op needs to hear.
