My girl is 3 and doesnt have a name yet but she watches lots of disney movies and wants to name herself cinderella should i let her what should i do?

Wow...Um no I don't think you should let her name herself because there are two things you have to consider: 1) Her career life 2) What people will think of her name and most importantly how comfortable you are with calling her whatever name is chosen for the rest of her life. Maybe not Cinderella, but perhaps she likes something girly or with Ella at the end. Here are some suggestions, ask her which one she likes:

Daniella
Gabriella
Isabella

I can't believe she doesn't have a name!

Maybe I dont get it but why doesnt she have a name at 3? what do call her? "Hey child come here"?

are you for real? im pretty sure you legally have to name your child long before they're 3. and if you are, no dont let her name herself cinderella, she will regret it when shes older. maybe something similar and girly, but not cinderella.

is that possible?

I suggest you name her something like Isabella, just DON'T name her Cinderella. And, as brought up by other people, is that even possible for her to not have a name at THREE?
