When are you sharing baby’s name? Am I wrong?

Looking for what others are doing, am I wrong for not wanting to share until birth

Hubby and I have been together for 9 years about six years ago we talked baby names and had thrown out name we loved including one for a boy in front of his mom and the reaction was horrible.

Fast forward we’re now pregnant with our first baby girl due March 20. Early on prior to sharing our news with anyone (8 weeks still) we found out his mom had shared with family before we were ready to share our exciting news. When it was time to tell *everyone knew* We had not decided on a girls name and also know how opinionated she is with names from the awful convo years ago. We together decided until we are 100% sure we aren’t sharing our name. 1)because of MIL opinions 2) it was fun for only us to know and it would be exciting to share upon birth.

So now We did decide on a name (but still could change upon birth right??? 🤦🏻‍♀️🤷🏻‍♀️ we couldn’t even decide on our dogs name my sister did). Last night MIL basically ambushed why we won’t tell her the name and that it is “malicious” that we are keeping it a secret because everyone else shares immediately. My husband responded “why are we keeping it a secret again” which fueled her fire. All of my family is respectful and so excited to meet baby girl/ladybug nickname that they gave her upon finding out we were pregnant. And all MIL asks about is tell me the name.

Am I wrong because I don’t want her opinion to the name? That’s the true reason we decided not to share when we did finally decide on a name? And two, what if we do change our mind upon birth!
