name trouble 😞

GF
So my boyfriend wants him to have his full name but all my police officer friends tell me it's a bad mistake like court and stuff wise and I want him to be Kayden dean Cregger but when we go to the hospital he's gonna sign the papers for his name as our boys name and I actually don't want that anyways How do I sign the papers before he does or however it works😞 (you can tell it's my first baby)Β
