Quick Answer
AAP guidance on HealthyChildren.org recommends sponge baths only until the umbilical cord stump falls off (usually one to two weeks). After healing, use a safe infant tub, 2 inches of warm water, and touch supervision—never leave your baby alone. Three baths per week is often enough in the first year because frequent bathing can dry newborn skin.
What Parents Need to Know
Bathing a newborn is a bonding moment, but it also raises practical questions: sponge bath or tub? How warm should the water be? When is the cord healed enough for immersion?
WHO guidance, reflected in AAP newborn bathing advice, recommends delaying the first bath until 24 hours after birth when possible. At home, most families shift from sponge baths to brief tub baths once the umbilical area heals.
Evidence-Based Guidance
AAP guidance states you should give only sponge baths until the umbilical cord stump falls off, which usually happens by about one or two weeks of age. If the stump remains beyond that time, talk with your baby's doctor.
For sponge baths, AAP guidance recommends gathering supplies first, laying baby on a padded flat surface, washing the face first with a damp cloth, then the body, and keeping baby warm by uncovering only the area you are washing.
Once the umbilical area is healed, AAP guidance says you can place your baby in water. First baths should be gentle and brief. Use a hard plastic infant tub that meets current safety standards. Avoid bath seats in adult tubs because they can tip over.
AAP guidance emphasizes touch supervision: keep a hand on your baby at all times. Never leave a baby alone in the bath, even for an instant. Most child drownings inside the home occur in bathtubs, and more than half involve children under 1 year.
For water temperature, AAP guidance recommends about 2 inches of water that feels warm—not hot—to your wrist or elbow. Do not bathe your baby in running water. The AAP recommends setting your water heater so the hottest faucet temperature is no more than 120°F to reduce scald risk.
AAP guidance notes that newborns do not need daily baths. Three baths per week during the first year may be enough because more frequent bathing can dry out skin. Use soap sparingly and rinse promptly.
WHO guidance, cited in AAP newborn bathing resources, recommends delaying the first bath until 24 hours after birth (or at least 6 hours when a full day is not culturally possible) to support temperature stability, bonding, and breastfeeding.
Practical Steps
- Gather supplies before undressing your baby—basin, washcloth, towel, clean diaper, and clothes.
- Sponge bathe until the cord stump falls off and the area looks healed.
- Test water temperature on your wrist; fill the tub with about 2 inches of warm water.

When to Contact a Clinician
Contact your pediatrician if:
- The umbilical cord stump has not fallen off by two weeks
- The cord area looks infected (redness, swelling, pus, or odor)

Seek emergency care if your baby is submerged unsupervised, becomes unresponsive, or shows signs of breathing difficulty after a bath incident.
