My daughter is almost 6months also low weight.yesterday she was not eating, & had watery, mucous yellow poop. nothing new in diet. what could this be?

DIARRHEA: Looks like mild viral diarrhea. If she has gotten 2 rota vaccines at 2 and 4 months, rota diarrhea is less likely.There are other many causes of viral diarrhea. Offer her pedialyte 4-6 ounces for each diarrhea. Give bananna, rice, applesauce, chicken/soup and continue breast feeding if you do. Diarrhea will resolve in 3-7 days. If any worsening or vomiting, higher fever, see her pediatirician.
