He is allergic to penicillan so he doesnt have it; hasnt had any antibiotics in months. Im wondering if its a food allergy or something like that. Someone mentioned ringworm to me; it looks a bit like the photos I googled but not enough for me to think its that. Plus we arent anywhere around cats and the like. And they havent been outside anywhere other than kindy and I bet they are pretty stringent about cleaning & the sandpit and stuff.
