Mother in laws 🙄

My fiancé thinks I'm crazy but we have a four year old that my in laws LOVE. we tried for 11 months to have another child. Now that we're finally pregnant, his mother is FURIOUS. Won't even acknowledge the fact I'm pregnant. Refused to come to gender reveal, won't even talk to me now. But still wants to take our daughter out of town (18 hours away!) I told them no, they aren't going to play favoritism towards our children. Am I being insane or not?
