C.V.
The reason he is picking at his scabs is because they are dry and they itch. Keep them moistened with an antibiotic ointment so that they don't get infected and leave scars and at night wrap them with a gauze where he can't get to them. Kids will do what they have to so that they are not uncomfortable or hurting, others just have a habit that they will have to grow out of. The more attention you place on this issue the more he will do it. Don't nag him about not peeling his scab, when you see him doing it just give him a look don't say anything to him. If no attention is given then the habit usually stops. It has worked for my children. Hope this helps.
