my three year old is allergic to sun cream. comes up in terrible blotches which are hot to the touch (actually looks a bit like sun burn, which foxed us at first). currently just using hat and long sleeved T shirts which are working a dream, he is not burning at all, but I don't think I want to go the whole summer like this. Any suggestions? was hoping to avoid a trip to the doctor for this but I guess it might be inevitable.
