Dad want to be part of birth

Kate
It may seem a little selfish but I just want it to be my husband and I there for the birth of our son. My dad told me he wanted to be there and at first I was fine with it but now I want it to just be us. My dad is just pushing for things too much, even going as far as the name saying we should name it after him, even though we already decided to name him after my husband. I'm just nervous he's going to be too pushy and make a beautiful experience miserable. Any one know how to let parents down easy or just what's the best way to handle this?
