My daughter, age 21 months, is experiencing vomiting, diahrea, and a rash around her belly button and knees.... It started about a week ago on the 31st and we went to the hospital. They said a virus and it did seem to get better after about 72 hrs. However, on the 5th at a follow up visit to the doctors she had a low grade fever and again it was dubbed a virus. That seemed to be the only symptom until last night the 7th of Jan. Yesterday she ate and drank normally. After we went to bed she seemed very agitated and uncomfortable. Her stomach was descended and hard. She threw up and after cleaning and going back to sleep she slept hard. When she woke up she had a very over filled diaper that smelled awful and had last night's food still in it. And now she has a rash around her belly button and on her knees. I am hoping for a possible answer that gives us insight as to why she might be experiencing these symptoms that we aren't receiving.
