I don't see y not it is still ur last name and ur other kids last names and if the other guy doesn't want the baby who cares what u name it :)
If you plan on keeping your married name as your last name then that is definitely the best thing to do. :-)
My mom gave my brother her maiden name even though she still has my dads last name. Just an idea.
Personally i wouldn't do it. I think baby should have the biological fathers last name (even if he doesn't want to be involved) or your maiden name. It does seem a bit weird especially if you are getting a divorce.
It's not weird. It's just a name really. Since you changes your name, it now belongs to you so you can give any of your babies that name. Make sense? It's a relationship to you because that's your name now, nothing to do with your ex.
