there's a good chance it could be psoriasis or eczema-both are skin conditions that my sister suffers from, and has since she was a baby (she's 39 now). I would definitely see your pediatrician, or see if you can get a consult with a dermatologist. neither are life-threatening, but they can be a real pain. my sister learned to control her outbreaks by changing her diet. hope this helps!
