my six year old daughter has had a vomiting and diarrhea bug that was quite mild but four days on the diarrhea is stil here and her stool is a beige foam and last night she was sick again but it contained food from 2 days before even though she has been going to the toilet regulary - before each toilet visit her stomach becomes very bloated and hard to the touch and she's very very windy. I'm worried that she may have a blockage somewhere? Please help.
