Ellie only BMs 1 - 2x daily...her stools have always been soft, then again, she's still only eating fortified breast milk. I've heard that CF babies pass stool more frequently if they are pancreatic insufficient (which she is). Every time we tell her dietician that she only has BMs 1-2x daily, she is always surprised. We've been trying to get her to gain weight, but she's truly not a big eater. She eats every 3 - 4hrs and that's even "forcing" her to eat. I keep reading that CF babies seem to have an insatiable appetite when they are PI - but Ellie doesn't seem to be this way....and yet...she's not gaining as much weight as her doctor would like. Any thoughts? Anyone experiencing something similar? FYI, she takes 1/2 capsule Pancrease MT4s with each feeding (2 - 4oz fortified breast milk), is 4.5mos old, weight 7.5lbs at birth, weighed 12lbs 9oz at last CF visit earlier this month....
