MIL told everyone my baby name and I wanted to wait till birth 😭

I told my husband I didn’t want to share our first baby name till she was born and we agreed. He ended up telling his mom cause she kept asking, and she told everyone and her niece who was due 3 months before me used the name and it made me sooo mad. This post isn’t for ppl that think it’s just a name why does it matter. 🙄 I just felt like it was wrong and the name wasn’t a common name it was unique that we came up with so I’m pissed 😡😡😭
