I took him to the doctors and he seems to think its heat rash or a viral thing he has had some funny poos too lately has anyone had issues with heat rash and how do I get rid of it he has a fan on in his room most nights and he doesn't sleep with a blanket (he is all over the place in his cot at night) just goes to bed in summer pjs.
