Has anyone ever heard of a 2 week newborn having acid reflux?  Dr. thinks my newborn may have acid reflux, to explain her outbursts at night while feeding and off and on throughout the night.

my daughter had it when she was a new born and my nephew had it when he was a new born we had to feed them when they were sitting stright up and we couldnt lay them down flat for like 30 minutes after they ate but it wasnt nothing too bad except they had it pretty bad they would spit up really bad alot of the time if we layed them down to early
