DH and BM came up with a schedule for kingergarten graduation day. BM's family has sd's for a few hours over lunch and then we get them for dinner. BM just notified DH today that sd was invited to a party that day that will cut in to our time. We already have our family coming at a certain time and would like the girls with us at the time that was set. Do we tell BM that we don't think she needs to go to her friend's party or that we'll pick her up at the party at the time that we were originally going to get them? (BM said she would drop them off after the party, but she's consistently late so who knows what time we would end up seeing them) I understand that kids need to balance friend and family time, but is it too much that they already have two celebrations to go to that day? In your opinion, should we make the friend's party happen some how or is this one time that we just need to say no?
