Has anyone’s husband not been there for the labor?

My boyfriend is from England and he is leaving here September 4th then coming back once our marriage paperwork is done, but he’s more than likely going to miss me giving birth in March. I know I can give the baby his last name but how can I get his name on the birth certificate?
