I am so frustrated-- in reality I know gas isn't the end of the world but the sleep disruption is ridiculous at this point!

My 3 month old is really gassy, while I feed her I can hear air moving around in her belly. During the day we can usually manage it buy at night she is frequently up hourly fussing. She usually goes right back to sleep but I can't keep waking up 14 times a night. She sleeps on her side which I think makes it worse so I frequently roll her back to her back but if I am lucky she passes gas and rolls right back, usually she rolls beck before she can even get anything moving.

Any ideas? She stopped pooping at night which I thought was good news since I could be done changing her diaper at night but I seem to be getting less sleep this way.
