Parenting between homes is by nature an adversarial process so co-parenting needs to be cooperative and you need a good attitude. Remind yourself you’re on the same side-the side of the child. You’re trying to bless your child emotionally, spiritually, and behaviorally, not get your way. And, unless proven otherwise, presume the other home in competent to function without you. Respect their boundaries, give up control, and let them do things their way. Parents need good attitudes, too.
