How Often Should I Change My Newborn’s Nappy?

Change your newborn’s nappy whenever they have done a poo, and check for wetness around every two to three hours during the day. Many newborns need about 8 to 12 nappy changes in 24 hours, although there is a wide range. Disposable nappies with a wetness indicator can make checking easier.

You do not usually need to change a sleeping baby after every small wee if their skin is healthy and the nappy is absorbent. Change them promptly after a poo, if the nappy is very wet or leaking, or if they have nappy rash or broken skin. Feeding times are convenient opportunities to check, but follow your baby’s cues rather than a rigid schedule.

When should I check my newborn’s nappy?

In the early weeks, check your baby’s nappy before or after each feed and whenever they seem unsettled. Because newborns often feed 8 to 12 times in 24 hours, this naturally creates regular opportunities to check. A nappy may also need changing after a nap, before leaving home and before settling your baby for a longer sleep.

Useful times to check include:

• Before or after each breastfeed or bottle feed
• As soon as you notice or suspect a poo
• When your baby wakes from a nap
• If the nappy feels heavy, looks full or is leaking
• If your baby seems uncomfortable or has irritated skin
• Before a longer sleep or journey

Some babies dislike being changed when hungry. If the nappy contains only urine and is not leaking, you can feed first and change midway through or after the feed. If it contains poo, change it promptly, then offer the feed and comfort.

Should I change a poo nappy immediately?

Yes. Change a poo nappy as soon as reasonably possible, including overnight. Poo contains digestive enzymes that can irritate delicate skin, particularly when left in contact with it. Prompt changes are especially important if your baby has diarrhoea, nappy rash, sensitive skin or broken areas.

Newborn poo can be frequent, and some breastfed babies poo during or shortly after most feeds. Others poo less often once feeding is established. Frequency alone varies widely; consistency, colour, feeding and your baby’s overall wellbeing provide more useful information. For more detail, see how often a newborn should poo.

Do I need to change a wet nappy straight away?

A wet nappy does not always require an immediate change. Modern disposable nappies draw moisture away from the skin, so a small amount of urine can usually wait until the next feed or routine check. Aim not to leave a very wet, heavy or leaking nappy in place.

Reusable nappies may feel wet sooner because their materials handle moisture differently. They often need more frequent checks and changes. Whichever type you use, adjust the timing to suit your baby’s skin, comfort and urine output.

If your baby is premature, unwell or receiving medical care, follow the changing and skin-care plan provided by your neonatal or maternity team.

Should I wake my newborn for a nappy change?

You generally do not need to wake a settled, healthy newborn solely for a small wet nappy. Check and change them when they wake to feed. However, wake or gently rouse your baby enough to change them if they have done a poo, the nappy is leaking or very full, or their skin is sore.

During overnight feeds, keep the room dim and your movements calm. Have supplies ready, use a quiet voice and avoid unnecessary stimulation. If your baby tends to poo while feeding, changing midway through or after the feed may prevent two changes. Always place your baby on their back in their own clear, flat sleep space once the feed and change are complete.

How many wet nappies should a newborn have?

Wet nappies are one helpful sign that feeding and hydration are progressing. During the first few days, urine output normally increases as milk intake increases. By around day five, most babies should produce at least six clearly wet disposable nappies in 24 hours. Reusable nappies may make wetness easier to feel but harder to compare by weight.

Your midwife or maternal health nurse can explain what to expect for your baby’s age and nappy type. Urate crystals, which can look like orange, pink or brick-coloured dust, may appear in the first few days. Tell your care provider if these continue beyond the early days, become more noticeable, or occur alongside fewer wet nappies or feeding concerns.

Counting nappies can be useful while feeding is being established. A note on your phone or a simple paper record is enough; there is no need to measure every nappy unless your healthcare professional asks you to. Visit the Baby Hub for more practical newborn care guidance.

How to change a newborn safely

Prepare everything before you begin: a clean nappy, warm water and cotton wool or fragrance-free wipes, a change of clothing and a nappy bag or bin. Use a stable changing surface or a mat on the floor. Keep one hand on your baby whenever they are on a raised surface, and never leave them unattended, even briefly.

To change the nappy:

• Wash your hands and place your baby safely on their back.
• Open the nappy and use its clean front section to remove most poo.
• Clean gently from front to back, including within skin folds, without scrubbing.
• Pat the area dry or allow a short period of nappy-free air time.
• Apply a thin layer of barrier cream if the skin is prone to irritation or as advised.
• Fasten the clean nappy snugly but not tightly; you should be able to slide two fingers beneath the waistband.
• Wash your hands after disposing of the dirty nappy.

For babies with a penis, point it downward before fastening the nappy to help reduce leaks. There is no need to retract the foreskin. For babies with a vulva, wipe from front to back and clean only what you can see externally.

Preventing and managing nappy rash

Frequent changes, gentle cleaning and allowing the skin to dry can reduce irritation. Avoid vigorous wiping and heavily fragranced products. A thin barrier layer can protect the skin from urine and poo; follow the product instructions and advice from your healthcare professional.

If redness appears, increase the frequency of changes and offer short periods without a nappy when practical. Make sure the nappy is not too tight. You do not need to remove every trace of barrier cream at each change if that would require rubbing; gently remove visible soiling and add a fresh thin layer.

Persistent or worsening rash may be caused by irritation, thrush, bacteria or another skin condition, and the treatments differ. Ask a maternal health nurse, midwife, GP or pharmacist to assess it rather than repeatedly changing products.

When to seek help

Contact your maternal health nurse, midwife or GP promptly if your newborn has fewer wet nappies than expected for their age, has no wet nappy for 8 hours, is feeding poorly, repeatedly vomits, develops persistent diarrhoea, or has a nappy rash that is worsening, blistered, bleeding, weeping or not improving after a few days of careful home treatment.

Seek urgent medical advice if there is blood in the urine or poo, black poo after the first newborn meconium has passed, very pale or white poo, a swollen abdomen, or signs of dehydration such as a very dry mouth, a sunken soft spot, unusual sleepiness or reduced responsiveness.

A temperature of 38°C or higher in a baby under 3 months needs urgent medical assessment. Contact emergency services immediately if your baby is difficult to wake, floppy, struggling to breathe, has blue or grey lips or skin, has a seizure, or seems seriously unwell. Trust your instincts: if something feels wrong, seek help.

A flexible routine works best

For most newborns, checking at every feed and changing promptly after poo provides a simple, responsive routine. Some days involve many changes; others involve fewer. Focus on keeping your baby comfortable, protecting their skin and noticing their usual feeding and nappy pattern rather than meeting an exact daily number.
