Excellent advice from this woman ^^. As someone who has been through two births with my wife, I'll second the idea that you get the plan together with your wife. Let her decide who is in the room. I cannot imagine she would want him in there watching as it all goes down. And make sure that you've got that plan, and talk it over with the doctor beforehand. You make sure the plans are taken care of so that she doesn't have to. You'll be her hero for taking care of all those stressful details and letting her just be. Also, when your baby comes out and they clean it and clamp the cord, the doctor WILL look right at you and ask if you want to cut the cord. Even if your seriously messed up FIL gets in the room, which I doubt will happen, the doctor will not ask him, the doctor will ask you and only you. If you say no thanks, then the doctor quickly cuts it and moves on. If it is in your wife's plan to breast feed, then that baby will be on top of her in a matter of about 60 seconds after birth, then covered with a blanket. You'll be right by her side wide-eyed and amazed. No one else will even exist at that point. You'll just be staring at that little face laying on your wife. Next thing you know, either you will be prompted to help wrap up the child or the child will be taken to the neonatal care table to finish cleaning, aspirating if necessary, and getting wrapped up and warm. Then the doctor or nurse will hand that baby to you. By this moment during my first child's birth, my wife had delivered the after birth (do not watch that please for all that is holy do not watch that part) and was covered, so my parents and her mom were in the room. Once the doctor was finished with my daughter, she was handed directly to me. No one else was even considered at all. It was if, despite there being something like 15 people in the room, the doctor could only see me and my wife in the room.
