I would offer her Caleigh back early with no strings attached, forget the swapping of days thing. Just ask if she can take her early. The A-hole thing came about because you told her what you thought. Hmmmm. I would have called you much worse....
The coparenting relationship is what is most important for your daughter right now, nothing more, nothing less. If it was me, I would call Kim and say look, I have something I need to do Saturday night, do you want her back early or should I ask my mom to cover it. That's what you would want her to do right????
By the way, I have a 12 pack says your Tide are gonna get their asssss beat down...... Ian
