Eczema (also called atopic dermatitis), is a skin rash that often appears in the first year of life. Eczema usually shows up on a baby's forehead, cheeks, and scalp, but it can spread to the arms, legs, chest, or other parts of the body. Your baby's rash might look like dry, thickened, scaly skin, or it might be made up of tiny red bumps that can blister, ooze, or become infected if scratched. Eczema isn't contagious, but because it's intensely itchy, scratching can be a problem. Atopic eczema is partly inherited, but is also believed to be related to the mother's diet during pregnancy, the child's diet after birth, and other factors. Certain foods, such as cow's milk, chocolates, tomatoes, and nuts, may increase the risk of eczema in infants who are genetically predisposed to the condition. Breast-fed infants are less likely to have eczema, especially if the mother avoids eating foods suspected of triggering eczema. Eczema often worsens under conditions of stress.
