Grunting Baby

Dana
Does anyone else have a baby that grunts...a LOT? My baby grunts when he is gassy, which is a lot but the doctor said is normal, but also he does it in his sleep. It's this constant thing and sometimes it drives me crazy. I guess my question is, when does this end? My LO is going to be 6 weeks old in a couple days and this has been going on for over a month now. He sleeps in his own room in his crib but it keeps me awake through the monitor.
