I told her I was gonna put my last name in the baby's name, there's gonna be my last name and her sons last name, so both last names will be in the baby's name but she doesn't seem to like my idea. She seems like she only wants her sons last name. We have a baby girl that's 19 months and this is gonna be our 2nd baby. The 19 month old baby only has her sons last name not mine but this time I want to put mine. She said my 19 month old is not gonna feel good enough when she's older just because she doesn't have my last name in her name and she also said our new baby is gonna have to spell him/her whole name in school. What's her problem??
