When your baby wakes repeatedly at night, it can leave the whole family exhausted. Night waking is common in babies, and the reasons can vary with age, feeding needs, sleep patterns, comfort and health. The goal is not to force every baby to sleep through the night, but to build safe, predictable routines and recognise when extra help is needed.
Why might a baby not sleep at night?
1. Hunger or feeding needs
Young babies have small stomachs and may need feeds overnight. Growth spurts, feeding patterns and individual needs can all affect waking. Follow your baby’s feeding cues and ask your paediatrician before trying to reduce night feeds, especially for newborns or babies who were born prematurely or have weight-gain concerns.
2. Day and night confusion
Some newborns have not yet developed a settled day–night rhythm. During the day, let natural light into the room and engage in normal household activity. At night, keep feeds and changes calm, quiet and dimly lit.
3. Overtiredness or changing naps
Long periods awake can make some babies harder to settle. Conversely, a late or lengthy nap may reduce sleep pressure at bedtime. Watch your baby’s cues and adjust the routine gradually rather than relying on a rigid schedule.
4. A need for comfort
Babies may wake because they want closeness, reassurance or help settling. A consistent wind-down routine—such as a feed, gentle cuddle, song and a quiet room—can make bedtime more predictable.
5. Developmental changes
Rolling, crawling, new communication skills and separation anxiety can coincide with temporary sleep changes. These phases vary from child to child, and night waking alone does not necessarily mean something is wrong.
6. Discomfort or illness
A blocked nose, fever, eczema, reflux symptoms or other discomfort can disrupt sleep. Do not assume persistent crying is simply a sleep problem; discuss ongoing symptoms or concerns with a healthcare professional.

What can you try to help your baby sleep?
- Keep a simple bedtime routine. Repeat a few calming steps in the same order each evening.
- Make nights boring and calm. Use a quiet voice and low lighting for overnight feeds and changes.
- Look for early tired cues. Yawning, turning away or becoming less engaged may signal that your baby needs help settling.
- Offer age-appropriate feeds. Check with your child’s clinician before changing feeding frequency or amounts.
- Keep the sleep space safe. Place your baby on their back for every sleep, on a firm, flat, non-inclined sleep surface designed for infants. Keep pillows, loose blankets, toys and other soft items out of the sleep space. Room-share without bed-sharing, and avoid overheating.
- Share the workload where possible. Take shifts with another trusted adult and seek support if exhaustion is affecting your wellbeing.
Safe sleep: what parents should avoid
Do not use weighted sleep products, inclined sleepers, positioners or pillows to try to keep a baby asleep. Do not give sleep medicines, sedating antihistamines, herbal remedies or supplements to a baby unless specifically directed by a qualified healthcare professional. If you feel yourself dozing while holding your baby, place them in their own safe sleep space before you fall asleep.
When should you contact a doctor?
Seek urgent medical care if your baby has trouble breathing, blue or grey lips or skin, is unusually difficult to wake, has a seizure, or appears seriously unwell. A temperature of 38°C (100.4°F) or higher in a baby younger than 3 months requires urgent medical assessment. Contact your paediatrician for persistent crying, feeding difficulties, fewer wet nappies than usual, poor weight gain, repeated vomiting, or sleep changes accompanied by other symptoms.
Frequently asked questions
Is it normal for babies to wake at night?
Yes. Night waking is common, especially in newborns and young infants who need feeds and comfort. Sleep patterns vary, and uninterrupted sleep should not be expected at the same age for every baby.
Should I let my baby cry until they fall asleep?
There is no single approach that suits every family or every age. Respond to your baby’s needs, consider their age and health, and speak with your paediatrician before starting a sleep-training method, particularly for a young infant.
Does a longer daytime nap always cause night waking?
No. Daytime sleep needs change as babies grow. Look at the whole pattern—total sleep, feeding, mood and bedtime—rather than assuming one nap is the cause.
When will my baby sleep through the night?
There is no universal age. Development, feeding needs, health and temperament all matter. If you are worried about your baby’s sleep or growth, ask your child’s healthcare professional for advice tailored to them.
A gentle reminder for tired parents
Frequent night waking can be difficult, but it does not mean you are doing something wrong. Focus on safe sleep, responsive care and small routines that work for your household. If your baby’s sleep seems unusual for them or you are concerned about symptoms, your paediatrician is the best person to help you work out the next steps.
