Moms - i know the flu has gone around multiple times in my home, myself being the worst victim this year - but my little one has had consistent almost diarrhea like poopy diapers for the last 3 days. It’s so bad that he’s gotten a rash on his legs and underneath his testicles from being wiped so much (i use unscented, sensitive wipes) - so i know I’m not wiping him too hard or anything.

Any ideas (other than doctors visits because he’s negative for flu/sickness) of what could be causing the loose stools? He hasn’t changed his appetite or eating habits? 🤷🏻‍♀️
