Only husband in delivery room?

Is anyone else just having their husband in the delivery room? At first I wanted my mom too but she can sometimes be overwhelming. And I felt bad for my mil, so I said she could come in. Then, while we were in the car, she asked her husband (my FIL) if he was going to be in the room? Honestly who does that? That's disgusting. I know my mom will understand, but my mil will probably have a fit. So I'm thinking about not telling anyone I'm in labor. And inviting everyone after. What do you think?
