More often than not, if a parent relaxes efforts at skin maintenance, the child will react with more dry skin patches that need help. Less is more with cleansing products. Babies typically don't get very dirty. Wash with water only, adding soap every other bath. The soap should be mild, and perfume free.
Many doctors recommend Dove Scent Free for Sensitive Skin.
Pat your baby with a towel - don t rub. Friction can cause irritation. While your baby is still damp, apply a quality, perfume free lotion. Some examples of this would be Cetaphil lotion, or Eucerin. Many babies suffer from a condition called cradle cap.
