Washing a newborn requires sponge baths 2–3 times per week until the umbilical cord stump falls off, then transition to shallow tub baths using lukewarm water and mild soap.
New parents often worry about bathing a tiny, slippery baby for the first time. The process is straightforward once you know the right order and safety rules. The American Academy of Pediatrics recommends just three baths per week for newborns—more frequent washing dries out delicate skin. This guide covers the two-phase approach: sponge baths first, then tub baths after the cord detaches, with all the temperature, supply, and safety details you need.
Sponge Bath Phase: Before the Cord Falls Off
Until the umbilical cord stump dries and falls off (usually 1–2 weeks), keep it completely dry. Sponge baths prevent the stump from getting wet and infected. The World Health Organization advises delaying the very first bath by at least 24 hours after birth—or six hours if cultural reasons make a full day impossible.
What you’ll need: a bowl of lukewarm water (around 100°F / 38°C), a soft washcloth, mild fragrance-free baby soap, a towel, a clean diaper, and fresh clothes. Lay the baby on a flat surface (changing table, bed, or floor) covered with a towel. Keep one hand on the baby at all times if using a raised surface.
Cleaning order: Start with the face and eyes—use a fresh corner of cotton wool or washcloth for each eye, wiping from the inner corner outward. Then wash the neck, behind ears, arms, chest, tummy, and legs. Leave the diaper area for last. Pat dry gently after each section. Only wash the cord stump if it gets soiled with urine or stool; clean with a cotton ball dipped in warm water and pat dry completely.
Tub Bath Phase: After the Cord Detaches
Once the stump falls off and the belly button looks healed, you can move to tub baths. Use a hard plastic infant tub with a sloped, textured surface that prevents sliding. Avoid bath seats entirely—they tip over and create a drowning hazard.
Setup and safety: Fill the tub with just 2 inches (5 cm) of water—babies can drown in less than that. Target 100°F (38°C); test the water with your inner wrist or elbow. Set your home water heater thermostat below 120°F (49°C) to prevent scalding. Keep everything within arm’s reach before you start. Never leave a baby alone in the bath for any reason; if you must leave the room, take the baby with you. If bathing in a sink, turn the faucet off before placing the baby in standing water.
Bathing sequence: Cradle the baby’s head and shoulders with your non-dominant hand and support the body with the other. Lower feet in first. Wash the face with plain water and a soft cloth—no soap. For hair, cup your hand across the forehead so suds run sideways, not into eyes. Shampoo once or twice a week only if needed. Wash the body from neck down, leaving the genitals and bottom for last. Clean girls front to back to prevent infection. Lift the baby out supporting head and back, wrap immediately in a dry towel, and pat dry—never rub. Apply a fragrance-free, hypoallergenic lotion right after to lock in moisture.

Common Mistakes and Safety Caveats
Even quick errors can be dangerous. The most common: leaving the baby unattended, using water that’s too hot, or scrubbing delicate skin with soap. Soap dries out newborn skin—use it only on heavily soiled areas like the diaper zone. Wash hair once a week unless the baby has oily or thick hair. Never use cotton buds inside the ears; clean the outer ear gently with a washcloth corner. Don’t scrub or tug the skin—use gentle, massaging motions.
A quick-reference checklist for every bath session:
- Water temperature: 100°F (test with wrist)
- Water depth: 2 inches max
- Room warm, no drafts
- All supplies within reach
- Phone off or set aside
- One hand on baby always
- Cord dry until stump falls off
- Lotion applied immediately after patting dry
FAQs
When should I give a newborn its first bath?
The WHO recommends waiting at least 24 hours after birth to allow temperature stability and skin-to-skin bonding. If a full day isn’t possible, wait at least six hours. The AAP supports delaying the first bath for similar reasons.
How often should I wash a newborn’s hair?
Once or twice per week is sufficient. Newborns have delicate scalps, and over-shampooing can cause dryness or cradle cap. Use a mild baby shampoo only if the baby has noticeable hair, oily scalp, or is more active and sweaty.
What temperature should baby bath water be?
Aim for 100°F (37–38°C). Always test with your inner wrist or elbow—it should feel comfortably warm, not hot. Set your home water heater to below 120°F (49°C) to prevent accidental scalding during future baths.
