Im a ftm too but that is so rude of them to think that since she'll only be a newborn for a short period that they have to be all in the mix,wouldnt they assume that this being your first you'd want to enjoy her too?..tell your hubs they need to back off an give you a little space an time to adjust..
I have not done with in laws like that but my mother was like that when I had my daughter. I told her how I felt about her trying to play mommy with my daughter. I let her know she can give advice but not take over. So just talk to them and let them know how you feel about it and let know know they are welcome to give advice and help you but not take over. If they reall care they will understand.
And congrats anf good luck.
