How to Bathe a Newborn: Sponge Baths, First Tub Bath, Water Temp, and What Actually Matters

The first bath is one of those newborn moments that looks a lot bigger in your head than it turns out to be. A slippery, tiny baby, a bathtub, and about eleven things you're afraid of doing wrong. Good news: for the first couple of weeks, there is no bathtub. Newborns get sponge baths — no submerging, no tub, just a warm washcloth. And once you can use water, the whole thing is closer to five minutes than fifty.

Here is exactly how to do it, straight from the AAP and other primary sources, with nothing invented in between.

01How soon can you bathe a newborn?

Not right away. The World Health Organization recommends "waiting 24 hours or more before giving newborns a bath, if possible," as Cleveland Clinic reports — and most U.S. hospitals now follow that lead. In one hospital study Cleveland Clinic cites, pushing that first bath back "to at least 12 hours after birth increased rates of exclusive breastfeeding," with exclusive breastfeeding rates rising "from 59.8% to 68.2% after implementing delayed bathing practice."

A cold, freshly-bathed newborn is a tired newborn, and a tired newborn is harder to feed — Cleveland Clinic puts it plainly: "Cold can make babies more tired. And a tired baby is less likely to nurse." Leaving the vernix and the amniotic-fluid smell alone also helps: "There's a similarity in smell between amniotic fluid and a lactating breast," which supports those very early nursing sessions. If you're delivering in a hospital, you can simply ask your nurse to hold the first bath until at least 12 to 24 hours.

02Sponge baths only, until the cord falls off

This is the single most important rule of newborn bathing: no tub yet. HealthyChildren.org, the American Academy of Pediatrics' parent site, is direct about it — "only give your newborn sponge baths until the stump of the umbilical cord falls off, which usually happens by about one or two weeks of age." The AAP's guidance on the cord itself allows a little longer: "The umbilical cord stump should dry and fall off by the time your baby is 3 weeks old."

Either way, the rule is the same: keep the cord dry, and stick to sponge baths until it's gone and the belly button has healed. If your baby was circumcised, Nemours KidsHealth adds that tub baths wait "after the umbilical cord stump falls off and the circumcision heals" too.

03How to give a newborn a sponge bath

A sponge bath is nothing more than a wipe-down with a warm, damp washcloth — no basin under the baby, no submerging. The AAP describes a sponge bath as "like a regular bath, except you don't put your baby in the water."

Set up first. Everything within arm's reach before your baby is undressed.

Then the sponge bath itself follows the order the AAP gives: cleanest parts first, dirtiest last.

• Start with the face. "Use the dampened cloth to wash their face, being careful not to get water into their eyes or mouth" (HealthyChildren.org). Just water — no soap on the face.
• Then the rest of the body. "Dip it in the basin of water before washing the rest of their body" — behind the ears, under the chin, in the neck folds where spit-up hides, under the arms, and between the fingers and toes.
• Diaper area last. The AAP saves this for the end so you're not moving bacteria upward.
• Skip the cord. Don't soak the stump. The AAP's cord-care guidance is simple: "There is no need to use alcohol on the umbilical cord stump; just keep it clean" and "keep the diaper folded below the cord to keep urine from soaking it."
• Wrap and pat dry. The AAD says to "immediately wrap your baby in a towel for warmth," then pat — don't rub — them dry, paying special attention to skin folds.

04The first tub bath: how much water, how warm, how long

Once the cord has fallen off and the belly button is healed, you can move to a small baby tub or a clean sink. The numbers are simple and the same across sources.

• Water depth: two to three inches, no more. Nemours KidsHealth: "Fill the tub with 2 to 3 inches of warm (not hot) water." Cleveland Clinic says the same: "Fill a sturdy baby bath with no more than two inches of water."
• Water temperature: warm, not hot — about 100°F (38°C). Cleveland Clinic gives a specific target: "no more than about 100 degrees Fahrenheit (38 degrees Celsius)." Test it with the inside of your wrist or elbow, not your hand.
• Turn the water heater down. The AAP recommends "that the hottest temperature at the faucet should be no more than 120 degrees Fahrenheit (49°C) to help avoid burns."
• Don't bathe in running water. HealthyChildren.org: "Never bathe your baby in running water, and don't use a sprayer attached to the faucet. Water temperature can fluctuate as it moves through your home's pipes, and even small changes can cause scalds."
• Keep it short — about five minutes. Cleveland Clinic: aim to "keep your baby's bath to no more than about five minutes" so the water doesn't cool and your baby doesn't get chilled.

05How to hold your baby in the tub

You don't need a special grip — just one steady, non-negotiable rule: one hand always on your baby. Cleveland Clinic's instruction is exactly this: "Support baby's head and neck with your non-dominant hand. Use your dominant hand for cleaning," and "never rely on baby tubs to keep your baby safe" without a hand on your baby the whole time.

The AAP describes the same posture in the bath: your forearm along your baby's back, your hand cupped under the far armpit so the head rests on your wrist. It looks awkward the first time and becomes automatic by the third.

06The one thing you cannot skip: never leave them alone

07How often to bathe a newborn

Much less often than you'd think. HealthyChildren.org: "Newborns don't need a bath every day. They rarely sweat or get dirty enough to need a full bath that often. Three baths per week during baby's first year may be enough." Cleveland Clinic and Nemours agree — "two or three times per week" is the standard, because "newborns really aren't that dirty."

More frequent bathing tends to dry out newborn skin. The AAD is explicit: "If you notice your baby's skin is dry after bathing, apply a fragrance-free moisturizer or consider bathing your baby less." A quick wipe-down of the face, neck folds, and diaper area at each change handles the day-to-day; the actual bath is a two-or-three-times-a-week event.

08Common questions parents actually ask

What if my baby hates the bath?

Some newborns dislike the naked, uncovered feeling more than the water. A few things help: keep the room warm, keep the water at 100°F, drape a warm damp washcloth over their belly during the bath so they don't feel exposed, and keep it short. If it's still a scream-fest, sponge bathing longer — well past the two-week mark — is completely fine. Cleaner is not the goal; the goal is a baby who isn't traumatized.

Should I use soap on a newborn?

Very little, and never on the face. The AAD's guidance is "a mild, fragrance-free baby soap" for the body and "baby shampoo once or twice a week" for the hair. Plain warm water is enough most of the time — newborn skin doesn't need much.

What about the cradle cap on my baby's scalp?

Those yellowish, greasy scales are cradle cap, and they're harmless. Gentle baby shampoo once or twice a week, along with a soft brush during the bath, is the standard approach. If it spreads, gets red, or looks inflamed, mention it at the next pediatrician visit.

09Bath time isn't the hard part

The bath itself is a five-minute job with a very short rulebook: sponge baths until the cord falls off, water at about 100°F and no more than two to three inches, two or three baths a week, and never look away. The rest of the newborn learning curve — feeding, burping, sleep, when to call the doctor — is on our newborn basics guide, each piece sourced the same way this page is.

And if you're still pregnant and mapping out the last few weeks, our free week-by-week planner puts the small setups — a baby tub, a couple of hooded towels, a mild fragrance-free wash — right where they belong: in the calm before, not the scramble after. First-week nerves are covered in what to expect the first week with a newborn, and the daily rhythm of feeds around bath time is in our newborn feeding schedule.
