Babies don't get very dirty, so they don't need to be bathed daily, says Brentwood, Tennessee-based pediatrician Parnell Donahue. “Three times a week is usually enough, provided the diaper area is cleansed well after every bowel movement, and wet diapers are removed frequently,” he adds. A baby’s face should be rinsed after feeding, Donahue advises. Clean the skin folds under arms, on the neck and elbows daily as well. Infants with dry or sensitive skin should have baths less frequently to protect the skin.
