I feel like I've been out of the game too long to help
I have a friend with a 1 month old baby that she is EPing for. He is on zantac for reflux, does not have that pyloric stenosis or whatever it is called/spelled. She has been off diary for 2 weeks. She said her son spits up anywhere from .5 oz to 4 oz at a time and spits up often, and is really fussy. His poops are fine and his weight gain is fine.
Any thoughts or advice I could pass along??
