Gender Reveal Party Drama.. MIL 🙄

My husband has always wanted a gender reveal party. I agreed that we could do one, and coincidentally we will be able to have it the weekend of his 30th birthday, which is perfect!

However, when telling my MIL our plans, she advised she would not come because knowing the gender would “take something away from the experience” for her (🙄🙄🙄🙄). I told her that after we find out the gender she’s going to find out one way or another... especially because we will refer to the baby as he / she. She said “I don’t care if it slips but I don’t want anyone outright telling me”.

My husband has never stood up to his mom, and it’s always been her way or the highway. But I can see he’s disappointed she won’t be a part of that special day; especially since his father has recently passed.

SO, do I

A) have a conversation with his mom about how she has disappointed him, and how this baby is not about her but about the family her son is starting?

Or

B) don’t talk to her and have the party without her? And then let it slip to her right after what the baby’s gender is to rub it in her face lol
