I agree, put it in there. If it happens on the day it's a bonus, if not, then you were probably expecting it anyway. So please for your sanity sake, put it in there, then at the time and what their moods are like, and depending when the weeks fall, then you have the option of getting them. If you don't put it in there, you will kick yourself later. His mood might change once the orders are in place too, he "might" just be bitter right now in the negotiation stage LOL (or not haha). Sometimes I forgo things where I would like to have to kids too. I also think of the kids too and whether it would disrupt them because I want them, but they are planned to be at their dads. My XH is fully entitled to have them for fathers day if it falls on my week, but he hasn't asked for them yet, and I am counting about 6 fathers days....So that it doesn't "disrupt" him. If it is mothers day you could arrange the pickup and dropoff so that he doesn't have an excuse and he pickup/dropoff if he wants them or fathers day. That could be a compromise ?
