He has his fathers last name and it means nothing so I chose that way
I have a partner and all my kids are in my last name as I have strong family values and he hatez his last name and would consider changing his to mine of I wanted but its easier for medical information and all for mother and children to have same names
Keeping your father's last name sounds like a security issue you still have. When your child gets older he will ask why you do not have the same name as he and his father. It sounds like you had to deal with some rough challenges growing up. You are grown now and have a family of your own, why let the issues with your father put any kind of split on YOUR family. I believe sharing a last name is a bond and obviously so do you! Good luck in whatever decision you make! And congratulations on your family!
Well, presumably you felt the loss of your dad's attention when you were younger and now that he has stopped disowning you, it might be very psychologically important to you as a representation that he came around. (How did your mom feel about that name change? Was she glad too?) You will indeed have a different name from your child, though, unless you decide to give your child your last name instead of your husband's.
I've known married couples who both changed their names, and in one case a man who changed his last name to his wife's. I also know moms and dads who are the bio parents and have kids named after one or the other of them or a mix of both.
