It could be dermatitis rather than simple chapped lips. Is it possible he's allergic to something? Can you find some connection to the peeling, dry lips and some food (apples can be a culprit for some children because they are very acidic), clothing (especially wool), sunscreen etc? (My lips are allergic to suncreen and any lipsticks or gloss containing it and this sounds similiar). I would definately mention it to his pediatrician. He might be able to prescribe something. Vaseline will also help keep the peeling to a minimum and make his lips feel better.
