My daughter is 14 months old and she has has watery diarrhea and vomitting. When she was born she was perfectly healthy, but once I had to return to work I began to give her formula and that's when she began to have these complications. She began to have watery diarrhea and vomit. I took her to the doctor and they said she had gastroenteritis, but it's been a while now and she is still the same? Does anyone know what could possibly be wrong? Thank you.
