Momma's I need some advice. My daughter is due Feb 5th and I'm very concerned what to put on her birth certificate. Her dad and I are together but he got in some trouble and has been away for past 2 months and will probably miss the birth. He is so happy to be a dad and I know he wants to change but his history with substance abuse is pretty bad...he wants her to have his last name - we are not married yet. This is so important and I want to make the right decision. Any help ?
