What is a good remedy for baby having dry skin?

Moisturizer. To help with dry skin, bathe your baby with a mild soap, then apply a fragrance-free moisturizer while they are still damp. This helps to trap the moisture in the skin. You can apply the moisturizer several times a day as needed. Increasing the relative humidity in your home can also help.
Dry Heat. Need to increase mousture in the house, short baths, not too warm water, don't rub body to dry just pat dry, use moisturising skin lotion after bath and frequently.
Oatmeal soak,aquaphr. Oatmeal soaks, followed by lots of aquaphor. Dress baby in damp long underwear, then a long snuggly on top.
