If your baby has dry, itchy skin, try a soothing oatmeal bath. To make your own oatmeal bath, grind oatmeal in a blender or food processor until it’s finely pulverized. Sprinkle a half-cup of oatmeal into the bath as the water is running, and mix thoroughly. The water will look milky, and the tub will be slick. Allow your baby to soak for up to 15 minutes. You can repeat this up to three times a day.
