My daughter was a premie born at 35 weeks, since she was in the NICU they fed her Similac Neosure (made for premies) she's been drinking that since she's gotten home as well, now she's 3 weeks. I noticed she used to pass a bowel movement everyday, now it's every 2-3 days. It seems as though after the feeding, she grunts and cries and seems as though she's pushing to pass a bowel movement but when I check her diaper, it's only pee. Not sure if this is constipation (though when she does poop, it's wet stool and not hard and solid) Not sure if it's time to switch her to another formula. She has a doctors appointment on Wednesday but just wanted to ask for advice from you mommys :)
