I guess this is something I’ve got lucky with. Ex always asks me ahead in these situations which works for me because most of the time it’s fine. If you get a chance try to meet some of the other moms or parents at school/kid functions. Most of the time I end up communicating w/them if it’s my week. If you don’t have a problem w/some play dates on your time then maybe show her by example when you have something on her time. My ex will often parrot back an action, the way I ask her for something, etc.
