Thanks Willow, that is what the GP said but he isn't my usual GP and I felt like he thought I was overreacting, hey I've got a 13 month old covered in huge hives that are appearing before my eyes, of course I'm bloody overreacting....you stupid condescending fool I'm going to ask for another skin p*rick test, I don't want to find out by trial and error IYKWIM.

Squidipa: No runny stools or vomiting, in fact he has been really happy all day, including when he was covered in hives.

It's all very confusing and I'm probably making myself more worried by consulting Dr. Google
