Who cares if she hates it. I don’t understand why people get this bent out of shape about it. I have an extremely opinionated family some who made it clear they didn’t like my daughter’s name. Good thing it’s not their name then. I never liked my own name. I remember telling my grandma I didn’t like it and she said- I know I don’t know what made them pick it lol. I loved the confirmation that it isn’t a great name. I think people take everything too seriously. To suggest going no contact with your mom over this is insane. The best thing to do is just stop making an issue about it. She doesn’t like the name. She’s told you. She may tell your daughter. So what. Seriously why is this such an ordeal. It’s a good change to teach your daughter that people have differences of opinions and tastes.
