Any other EBF moms have trouble with LO having allergies ? I found out DD had an allergy when her diapers became full of mucus. I took her to the pediatrician and she had blood in her stool as well. i have cut all dairy, soy, nuts, and eggs from my diet for the past week and her reflux and diapers seemed to improve however.... We went to get breakfast 2 days ago and I asked if they use butter and the waitress said no. Well I'm dumb because the oil the used to cook the hash browns probably had soy in it and baby was vomiting yesterday, irritable and had at least 10 awful mucus poop diapers. its discouraging and I know she's hurting now.
