If what your child has is truly eczema, there is plenty that can be done for him. Keeping the skin well moisturized is one of the most important parts of both the treatment and prevention of eczema, but there are many other components of a successful program. These include the use of topical steroid ointments, which help control the itch as well as decrease inflammation in the skin, and oral antihistamines, which also help to control the itching. Sometimes antibiotics are also necessary if a secondary infection (usually caused by scratching) is present. I would recommend you have your son evaluated by a pediatric dermatologist (or a general dermatologist comfortable with the treatment of eczema). In the meantime, keep daily baths short (no longer than 10 minutes) and apply a thick moisturizing cream immediately after he finishes bathing. Also keep your son's nails trimmed, as they are the single most important source of bacteria in children with infected eczema. Good luck.
