I understand that you're tired of the topic of mixtures and poop. Here some moms are smarter than any pediatricians. Can you help ? We switched from Nutrilon to Nan for a month now. We've been having diarrhea with mucus all this time. What could it mean? Is it not the mixture? Or is it an allergy to cow's milk protein? What tests should we do to figure this out? A pediatrician needs to constantly tell us what specific test we need... I can't take it anymore, I'm tired of doctors' stupidity...
