I want to use the nickname "Mama" for my daughter
Why the name "mama"?
I just want to have a cute nickname for her.
I think it'd be cute to name your baby that. It would be a nice nickname and you can always stop using it.
Alright, thanks for the approval.
Nicknames are a nice way to show someone that you care about them. Usually we only use nicknames for someone that we like, so I'm sure your daughter will like it.
