Newborn Hygiene: Cord Care, Bathing and the Nappy Rash That Needs Treatment

Newborn skin is thinner than adult skin, absorbs more of what is put on it, and loses water faster. It also arrives with its own protection. Most of what parents are sold for baby care is unnecessary, and some of it does harm.
The useful advice is short: less washing, fewer products, and knowing the few warning signs that matter. This guide covers the umbilical cord, bathing, nappy rash, cradle cap, what to avoid, and when a baby needs a doctor rather than a cream.
🧴 The umbilical cord
The cord stump dries, turns black and falls off on its own, usually within one to three weeks. The current recommendation in most countries with clean water and good hygiene is dry cord care: keep it clean and dry, and leave it alone.
- 🧼 No antiseptics or alcohol routinely; they delay separation without reducing infection in healthy term babies at home
- 🪒 Fold the nappy down below the stump so urine does not soak it
- 💧 If it gets dirty, clean gently with water and let it air dry
- ✋ Do not pull a stump that is hanging by a thread; it will come away by itself
- 🧶 A little sticky discharge or a small amount of blood as it separates is normal
🔴 Signs of cord infection (omphalitis) — see a doctor the same day:
- Red skin spreading around the navel onto the abdomen
- Pus or a foul smell
- Swelling, heat or tenderness when touched
- Fever, poor feeding or unusual sleepiness
- Active bleeding that does not stop with gentle pressure
In newborns this spreads quickly and is treated with antibiotics in hospital. It is the one cord problem that must never wait.
🛁 Bathing: less often than you think
| Question | Answer |
|---|---|
| How often? | Two or three times a week is enough. Daily bathing dries the skin |
| First bath? | Delaying the first bath for at least 24 hours after birth helps temperature and blood sugar and keeps the protective vernix on the skin |
| Water temperature | About 37°C; test with your elbow or wrist, never only with a hand |
| How long? | 5 to 10 minutes is plenty |
| What to use | Plain water for the first weeks; then a mild, fragrance-free cleanser if you wish |
| In between | Top and tail: wash face, neck folds, hands and nappy area with water and cotton wool or a soft cloth |
Never leave a baby alone in water, even for a second. Babies can drown in a few centimetres. If the doorbell rings, take the baby out.
👶 Nappy area: preventing rash
Nappy rash comes from the combination of wetness, friction and the ammonia produced when urine and stool mix. Prevention is simple and works.
- Change often
- Every two to three hours in newborns, and straight after a stool.
- Clean gently
- Water and cotton wool, or fragrance-free and alcohol-free wipes. Wipe front to back in girls.
- Dry properly
- Pat, do not rub, and let the skin air for a few minutes before the new nappy.
- Use a barrier
- A thin layer of zinc oxide or petroleum-based barrier cream at each change if the skin is prone to redness.
- Do not use talc
- It can be inhaled and does not prevent rash.
🔍 Which nappy rash is it?
| Type | How it looks | Treatment |
|---|---|---|
| Irritant rash (most common) | Redness on the buttocks, thighs and genitals; the skin folds are usually spared | More frequent changes, air time, barrier cream. Improves in 2 to 3 days |
| Candida (yeast) | Beefy red, involves the skin folds, with small spots at the edges; often follows antibiotics | An antifungal cream prescribed by a doctor; barrier cream on top |
| Bacterial | Yellow crusts, blisters or pus, sometimes with fever | Needs medical assessment; antibiotic treatment |
| Allergic or contact | Sharply outlined redness matching a wipe or nappy edge | Change the product |
The fold test is the most useful clue at home: irritant rash avoids the creases, yeast lives in them. Antifungal and antibiotic creams for infants are prescription decisions. Related medicines are in our skin care and antifungal categories, including Bactroban (Mupirocin) for bacterial skin infection, but nothing should be applied to a baby without a doctor seeing the rash first.
⚠️ Do not use steroid creams meant for adults on a baby's nappy area. Skin there is thin and occluded by the nappy, which increases absorption and can thin the skin. Only a doctor should prescribe a steroid for an infant, and only a mild one for a few days.
🧴 Cradle cap and baby skin
Cradle cap is the greasy, yellowish crust on the scalp that appears in the first months. It is harmless, not caused by poor washing, and usually clears by itself. Softening the crusts with a little baby oil or plain vegetable oil for an hour, then washing with a mild shampoo and brushing gently with a soft brush, speeds it up. Do not pick at it.
Other normal newborn skin findings that need no treatment: small white spots on the nose (milia), a blotchy red rash with tiny pale centres in the first week (erythema toxicum), peeling skin in the first days, and baby acne at around 3 to 6 weeks.
🧼 What to skip
- Fragranced products, bubble baths and antibacterial soaps — irritate thin skin
- Talcum powder
- Cotton buds inside the nose or ears — clean only what you can see
- Cleaning inside a baby girl's labia or pulling back the foreskin in boys — both cause harm; wash only the outside
- Adult creams, herbal remedies and essential oils on newborn skin
- Daily bathing with soap in the first weeks
🧫 Nails, eyes and nose
Nails grow fast and scratch faces. File them or cut them straight across when the baby is calm or asleep, using baby scissors or clippers. Sticky eyes are common from a blocked tear duct: wipe from the inner corner outwards with cotton wool and cooled boiled water, using a fresh piece for each eye. Redness of the white of the eye, swelling of the eyelid or yellow-green discharge needs a doctor. For a blocked nose, saline drops before feeds help far more than suction devices.
🧑🤝🧑 Hand hygiene and visitors
A newborn's immune system is immature, and the most effective hygiene measure is not about the baby at all: it is about the hands that hold them.
- 🧼 Everyone washes hands before holding the baby
- 🤧 Anyone with a cold, cough or cold sore stays away; in newborns, the cold sore virus can cause serious illness, so no kissing the face
- 💉 Whooping cough and flu vaccination for parents and close family protects babies too young to be vaccinated
- 🚬 No smoking around the baby or in the home
🚨 Fever in a young baby is different
🔴 A temperature of 38°C or higher in a baby under 3 months is an emergency, even if the baby looks well. Young babies can have serious infection with very few signs. Do not give paracetamol and wait; seek medical care immediately.
Also seek urgent help for: refusing feeds, unusual sleepiness or floppiness, a bulging soft spot, fast or laboured breathing, a rash that does not fade when pressed, grunting, or a baby who is hard to wake.
Breathing patterns that worry parents but are usually normal are explained in our guide to newborn breathing.
📞 When to see a doctor
- Redness spreading from the navel, pus or smell — same day
- Nappy rash that is not better after 3 days, involves the folds, or has blisters or crusts
- Fever in a baby under 3 months — immediately
- Swollen eyelid or yellow-green eye discharge
- Any rash with fever, or one that does not fade under pressure — emergency
- Cold sore contact with a newborn
❓ Frequently asked questions
How often should I bathe a newborn?
Two or three times a week is enough. Daily bathing dries the skin. Between baths, wash the face, neck folds, hands and nappy area with water. Plain water is fine for the first weeks.
How do I care for the umbilical cord?
Keep it clean and dry and leave it alone. Fold the nappy below the stump, clean with water only if it gets dirty, and let it fall off on its own, usually within one to three weeks. Antiseptics are not needed routinely.
What are signs of an infected cord?
Redness spreading onto the abdomen, pus or a foul smell, swelling or tenderness, and fever, poor feeding or sleepiness. This needs medical care the same day, because infection spreads quickly in newborns.
How can I tell if nappy rash is a yeast infection?
Ordinary irritant rash spares the skin creases. Yeast rash is beefy red, involves the folds, and often has small spots at the edges. It frequently follows a course of antibiotics and needs an antifungal cream prescribed by a doctor.
What is the best treatment for nappy rash?
Frequent changes, gentle cleaning with water, drying and air time, and a thin layer of zinc oxide or petroleum barrier cream. Most rashes improve within two or three days. If not, or if there are blisters, crusts or fever, see a doctor.
Can I use adult creams on my baby?
No. Baby skin absorbs much more, and the nappy traps the cream against the skin. Steroid and antifungal creams for infants should be prescribed by a doctor who has seen the rash.
How do I treat cradle cap?
Soften the crusts with a little baby or vegetable oil for an hour, wash with a mild shampoo, then brush gently with a soft brush. It is harmless, not caused by poor hygiene, and clears by itself over time. Do not pick at it.
Should I use baby powder?
No. Talcum powder can be inhaled by the baby and does not prevent nappy rash. A barrier cream works better and is safer.
When is a fever in a newborn an emergency?
A temperature of 38°C or higher in a baby under three months needs immediate medical care, even if the baby looks well. Young babies can have serious infection with very few other signs.
Can visitors hold my newborn?
Yes, with clean hands and if they are well. Anyone with a cold, cough or a cold sore should stay away, and nobody should kiss the baby's face, because the cold sore virus can cause serious illness in newborns.
