There are many reasons why a baby might suffer from eczema, but one of the most common is an allergic reaction to something in their environment. For example, they may be allergic to the soap or detergent used to wash their clothes, or to the pollen in the air. Eczema can also be caused by a reaction to food, such as milk or eggs.   Some babies are just born with a tendency to develop eczema, and there’s not much that can be done to prevent it. In some cases, it might go away as the baby gets older, but in others, it may continue to be a problem.   If your baby has eczema, it’s important to keep their skin well-moisturized. You can do this by using a moisturizer that’s specifically designed for eczema-prone skin. You should also avoid using any products that contain harsh chemicals or fragrances, as these can irritate the skin.
