My 6 month old baby has eczema, and he scratches real bad. what can i do to stop the itching and scratching?

Atopic dermatitis: Now known to be shortage of omega-6 and omega-3 fatty acids. He needs a mixture of 1 part gla to 4 parts epa, not linseed or canola oil. See a nutritionist.

He needs to be seen: Your child should be seen for treatment. In the meantime oatmeal baths can help with the itching. You could also try otc topical steroids until you can be seen.
