For a newborn, it is recommended to delay the first full bath until at least 24 hours after birth, or at least 6 hours if culturally necessary, according to the World Health Organization. During the first few weeks, until the umbilical cord stump falls off and the area has healed, sponge baths are safest. After this, you can start tub baths. Bathing 2-3 times a week is generally sufficient to keep a newborn clean, and daily baths are not necessary as they can dry out the baby's skin. The best time to bathe your newborn is when you and the baby are relaxed, and ideally not right after feeding or when the baby is hungry or tired. Bath time can also be a good way to help settle the baby for sleep in the evening if desired.
