Bathing a baby safely requires lukewarm water around 100°F, a shallow 2–3 inch depth, mild fragrance-free soap, and never leaving the baby unattended for even one second.
The key rules are few: keep water warm but not hot, use soap only where needed, rinse thoroughly, and always keep one hand on the baby. This guide covers sponge baths for newborns and tub baths for older babies with exact safety steps.
What You Need Before Starting
Gather everything before undressing the baby; you cannot step away once the bath begins. You’ll need a baby tub, sink, or clean basin; two soft towels; a washcloth; mild fragrance-free baby soap; cotton wool; and a clean diaper and clothes. If the baby has hair, have baby shampoo ready. Fill the tub or sink with no more than 2–3 inches of water at 100°F (37.8°C – 38°C; test on the inside of your wrist or elbow — it should feel comfortably warm). A bath thermometer removes guesswork, but the wrist test is reliable. Keep the room warm and draft-free.
Sponge Baths for Newborns (First 1–2 Weeks)
Until the umbilical cord stump falls and circumcision (if applicable) heals, stick to sponge baths. Wrap the baby in a towel and expose only the area you’re washing.
Face first: Use plain water and cotton wool — no soap. Clean each eye from the inner corner outward with a fresh piece of cotton wool. Wash the rest of the face with water only. Clean the outer ears with a damp cloth; never insert anything into the ear canal. Wash the head: Wet hair, apply a tiny drop of mild soap or shampoo, rub gently front to back, rinse thoroughly with a wet cloth, and pat dry immediately. Body and diaper area: Support baby’s head and back with your arm, then lather soap from the neck down. Clean between fingers, toes, and every skin fold. For the diaper area, always wipe front to back. On uncircumcised boys, do not pull back the foreskin — clean only what’s visible. Rinse each area with a clean wet cloth and pat dry before moving to the next section.
Tub Baths Once the Baby Can Sit
Once the cord heals and the baby can sit with support (usually 1–2 months), move to a shallow tub bath. Lower the baby feet-first, keeping most of the body above the water line. Pour warm water over the chest and shoulders periodically to maintain warmth. Wash face and scalp first (shampoo once or twice a week), then work down the body with soap, paying attention to creases at the neck, behind the ears, and between fingers and toes. Rinse each area after washing — leftover soap residue dries delicate skin. Lift out and wrap in a towel immediately. If skin looks dry, apply fragrance-free moisturizer, but avoid the face.

Critical Safety Rules Every Time
- Never leave the baby alone in water — not for a second. Gather all supplies beforehand. Do not trust older children or bath seats to supervise; bath seats can tip and are not safety devices.
- Set your water heater below 120°F to prevent scalding. Turn off the faucet before placing the baby in the sink, and use a spout cover if in the tub.
- Keep baths short — 5 to 10 minutes. Bathing 2–3 times per week is sufficient for newborns; daily baths are fine if the baby enjoys them but aren’t necessary.
- Avoid common mistakes: don’t use soap on the face, don’t skip rinsing (it dries the skin), and never bathe an overly hungry or overtired baby.

|---|---|---|
| Sponge bath | First 1–2 weeks (umbilical cord not yet healed) | Wrap in towel; wash face with water only; use soap from neck down; rinse and pat dry area by area |
| Tub bath (sink or baby tub) | After cord heals, baby can sit with support | Feet-first entry; wash face and scalp first; soap body; rinse thoroughly; wrap immediately |
| Water temperature | Every bath | 100°F (37.8°C – 38°C); test on wrist or elbow |
| Water depth | Newborns: 2 inches; older infants: max 3 inches | Fill before placing baby in tub |
| Soap/shampoo | As needed | Fragrance-free, hypoallergenic; shampoo 1–2 times per week |
| After bath | Immediately | Pat dry; moisturize dry skin (avoid face); dress quickly |
FAQs
Can I bathe my baby every day?
Yes, if your baby enjoys it and doesn’t have dry skin. For newborns, 2–3 times per week is sufficient. Daily baths are fine as long as you keep them short (5–10 minutes) and use mild soap sparingly.
How do I know if the bath water is too hot?
Test water with the inside of your wrist or elbow — it should feel comfortably warm, not hot. A bath thermometer is most reliable; aim for exactly 100°F (37.8°C). If it feels hot to your wrist, it’s too hot.
Should I use baby powder or lotion after a bath?
Fragrance-free moisturizer is fine if baby’s skin appears dry, but skip the face. Avoid baby powder entirely — the American Academy of Pediatrics advises against it because fine particles can irritate a baby’s lungs.
