Most hospitals now recommend waiting at least 24 hours after birth before giving your newborn their first bath. Many parents are surprised by this, especially since bathing right after delivery was standard practice for decades. But the delay has clear benefits: it helps your baby stay warm, keeps blood sugar stable, and gives breastfeeding a better start.
Why the First Bath Is Delayed
Newborns are born covered in a white, waxy coating called vernix. It looks like it should be washed off, but it actually serves as a natural moisturizer, a waterproof barrier, and even has antibacterial properties that help protect your baby’s skin in those first vulnerable hours. Washing it away too soon strips those benefits.
A systematic review published in the Journal of Global Health looked at studies comparing early bathing (within the first 24 hours) to delayed bathing (after 24 hours). Delaying the bath by at least 24 hours roughly cut the risk of hypothermia in half and was associated with lower infant mortality, though the evidence was graded as low certainty. Even waiting just 6 hours made a meaningful difference: babies bathed after the 6-hour mark had about half the rate of dangerous drops in body temperature, were significantly less likely to develop low blood sugar, and were more likely to be exclusively breastfeeding at discharge.
The blood sugar connection makes sense when you think about it. A bath is stressful for a newborn. Their body burns extra energy trying to warm back up, which pulls from already limited glucose stores. Keeping your baby skin-to-skin instead of bathing them gives them time to stabilize and begin feeding.
Sponge Baths Until the Cord Falls Off
Once you’re home, sponge baths are the way to go until the umbilical cord stump falls off, which typically happens 1 to 3 weeks after birth. The goal is to keep the stump dry so it separates cleanly. While getting the stump briefly wet won’t cause harm, a full tub bath makes it harder to keep the area dry.
For a sponge bath, gather everything you need before you start: a basin of warm water, a couple of washcloths, a towel, mild baby soap, and a clean diaper and outfit. Lay your baby on a padded flat surface like a changing table or a towel on the floor. Undress them and wrap them in a towel, exposing only the area you’re washing at a time to keep them warm.
Start with the face using just water and a damp cloth, no soap. Work your way down the body, cleaning between all the skin folds, between fingers and toes. Save the diaper area for last. Pat dry rather than rubbing. The whole process can take just a few minutes, which is a good thing since most newborns are not fans.
If Your Baby Was Circumcised
A circumcision adds a separate timeline. The healing area needs to stay out of standing water for 7 to 10 days, so stick with sponge baths during that window. At each diaper change, gently squeeze water from a wet cloth over the penis and pat it dry. Don’t rub. You’ll likely see redness and a yellowish film over the area, both of which are normal parts of healing. Apply petroleum jelly at each diaper change to keep the area from sticking to the diaper.
Switching to a Tub Bath
Once the umbilical cord stump has fallen off (and the circumcision site has healed, if applicable), you can move to a regular tub bath. Use a small baby tub or basin with just a few inches of water. The ideal water temperature is around 100°F (38°C). Always test it with the inside of your wrist or elbow before placing your baby in. As a general safety measure, set your home water heater to below 120°F to prevent accidental scalding.
Keep one hand on your baby at all times during a tub bath. Newborns are slippery when wet, and even a couple of inches of water poses a drowning risk if they slip under. Have your towel, soap, and clean clothes within arm’s reach before you begin so you never need to step away.
How Often Newborns Need a Bath
Less often than you’d think. The American Academy of Pediatrics and the American Academy of Dermatology both recommend no more than 2 to 3 baths per week for newborns. Bathing more frequently can dry out their delicate skin, which is still developing its natural moisture barrier. In between baths, a quick wipe-down of the face, neck folds, and diaper area is enough to keep your baby clean.
Signs of Trouble at the Cord Site
While cleaning around the umbilical stump during bath time, keep an eye out for signs of infection. Redness or discoloration spreading around the base of the stump, skin that feels hard or thickened, fluid that looks yellowish or smells bad, and tenderness that makes your baby cry when you touch the area are all warning signs of a condition called omphalitis. This is uncommon but serious, and it needs prompt medical attention. A little bit of dried blood or slight moisture at the base as the stump separates is normal and not a cause for concern.
