Petty of me to say this?

Okay so this is mine and my husband’s first baby. We struggled with losses back to back prior and this child is really special to us. His mother (who literally I think has always hated my guts) is hosting a shower for us 11 days before my due date— pushing it close— but we have been so thankful! She posted the event on FB and included his name in the title although we haven’t announced it yet publicly. People at our first shower, and immediate family and friends know, but it’s been 100% kept off social media. I sent this to her today asking her to change the name of the event and wondered if you guys think I’m being petty or if I’m wrong for asking?

Part of me feels petty and feels like she may come back with some ridiculous response about getting over it, but I really wanted to be able to announce his name once he was here and for it to be a semi surprise to people. I don’t really have a good reason to explain, but I just wanted that. Please help!

UPDATE:

She actually took this very well. Her response made me wonder, as she simply said “sure”. But she hasn’t been hateful or hostile at all after the fact and things have been going seemingly better. I’m actually glad I asked her & I hope that things can continue being good for us like this, seeing how our relationship in the past has been VERY rocky. Figured I’d post this update for anyone who cared to know! Thanks guys for your input! 💕
