My daughter has sand coloured loose stools, which smell almost chemical as does her wind. she is very hot and had a sick bug 4 days ago, any advice?

Not sure what you: mean by "a sick bug," but if you mean she was vomiting, then it sounds like she might have a gastrointestinal virus ("stomach bug"). If she has fever, she can have acetaminophen. For the stools, try to give her a more binding diet, stay off dairy and lots of fluids. Have her seen by her doctor if she is not eating/drinking or not getting better.
