Eczema is a form of dermatitis, or inflammation of the epidermis or the outer layer of the skin. Baby eczema is a common skin condition that can start as early as just a few weeks. It causes redness, swelling, crusting, itching, and it requires a greater use of baby gloves than usual. It can cause fluid filled bumps as well as severe pain in infants and toddlers in some cases.
