6 week old baby wont sleep on back due to reflux ?????????

My niece has baby reflux. She has never slept in her bouncer/swing/car seat as a "solution." Try to have your daughter sleep on her side in her crib. You can either buy an infant positioner or just roll up a small blanket or towel, rubber band it, and prop it behind her. This worked great for my sister; I hope it works for you!
