The order as you've quoted it to us doesn't give mom an equal say - it merely requires dad to "provide the mother notice of the daycare/program in which HE intends to enroll the child". We have no access to the order beyond what you've described, but going on that language mom's mere wish that she had a 50% say, despite having no actual objection to the preschool or religious aspect, isn't going to get her very far.
What opinion does Mom want to share, other than "I wish I had more control when the children are with you, regardless of what our order says"?
