You may want to use a very small amount of oil on the scalp. Whether or not you use oil the scaliness usually disappears in a few weeks. A baby's skin is so lovely that it doesn't need anything special. Oils, powders, and lotion are not necessary. Bath time is a good time to play with your baby as it provides a chance for exercise by kicking and moving around.
Many mothers feel babies sleep better after a bath.
Bathe the baby at a convenient time for you and the family. The umbilical cord was cut and tied after birth. It dries up and falls off in about a week. In the meantime, do not tub bathe your baby. This will not hurt or sting the baby.
