It's one of the most common newborn questions, and the instinctive answer — bathe them daily, like everyone else in the house — turns out to be wrong. Newborn skin doesn't need it, and over-bathing can actually cause problems.
How often to bathe a newborn
The American Academy of Pediatrics recommends three baths a week during a baby's first year, noting that bathing more often can dry out sensitive newborn skin. The NHS gives a similar range — two to three times a week is enough — while noting there's no harm in bathing more often if your baby genuinely enjoys it.
For the first four weeks specifically, the NHS recommends plain water only, with no soaps, shampoos, or lotions, since early exposure to those products can contribute to allergic reactions or eczema. The waxy vernix coating some babies are born with should be left to absorb into the skin naturally rather than scrubbed off.
When to give the first bath
The World Health Organization's newborn care guidance recommends delaying a healthy, full-term baby's first bath for at least 24 hours after birth, specifically to reduce the risk of hypothermia.
Sponge baths vs. tub baths
Until the umbilical cord stump falls off — usually around one to two weeks — the AAP recommends sponge baths only, rather than submerging your baby in water. Once the cord area has healed, baths should still be brief and gentle.
Umbilical cord care while bathing
There's no need to use alcohol on the cord stump — just keep the area clean, and fold the diaper down below it so urine doesn't soak it. A few drops of blood around the time the stump separates is normal. The NHS advises only cleaning around the cord if it's actually dirty, using fresh cotton wool and warm water, then patting it dry.

New guides go out the moment they're published — no noise in between.
Call your pediatrician if the umbilical cord actively bleeds, or if you notice foul-smelling yellowish discharge, red skin around the base of the cord, or your baby crying when the cord or surrounding skin is touched — these can indicate an infection that needs treatment.
Getting the water temperature right
Fill the basin with about two inches of water that feels warm — not hot — against the inside of your wrist or elbow. The AAP recommends setting your water heater so the hottest tap temperature never exceeds 120°F, specifically to prevent scald burns. The NHS gives the same wrist-or-elbow test, running the cold tap first and then adding hot water so there are no unmixed hot patches.
Never leave a baby alone in the bath, even for a few seconds — use "touch supervision," meaning a hand on your baby at all times. Both the AAP and NHS specifically advise against bath seats and rings: they can tip over, and a baby can drown in just a few centimeters of water, silently and within seconds.
