My 4 month old baby has had green, mucousy poop for the last week or so now. She seems to blow out of her diaper almost every day. She is breastfed and has always been a "powerful" pooper, but since her poop has become so runny, it almost always seems to run out the back of her diaper. Anyone else every had this happen? I have heard/read it could be teething or an allergy. I plan on calling my ped tomorrow but was just wondering if any other moms had any experience with this. Thanks!
