The short answer
Night waking at 31–36 months may relate to routine changes, discomfort, fears, nightmares or partial arousals such as night terrors. Check basic needs and illness, keep the response quiet and consistent, and seek medical advice for breathing problems, pain, unusual episodes or persistent disruption.

Keep in mind
- Children aged 3–5 are generally recommended 10–13 hours of sleep per 24 hours, including naps; how this is distributed varies.
- When a child wakes, first consider pain, illness, room conditions and basic needs such as using the toilet.
- A brief, calm and consistent response can be more helpful than changing the approach at each waking.
How can you sort through possible causes?
Ask whether the waking is new, happens at a similar time, follows a late nap, includes a fear your child can describe or comes with pain or illness. With a nightmare, a child often wakes fully and seeks comfort. During a night terror, they may look awake but not be fully awake; keep them safe and do not try to force them fully awake.
What can you change in the evening routine?
Use a similar sequence each night, such as toilet, brushing teeth, a short book and a calm goodnight. Keep the room dark, cool and quiet; avoid lively play and screens close to bedtime. If you change something, choose one adjustment and observe it for several nights.
How should you respond when your child wakes?
First check for illness, pain or fear. Keep lights and conversation low, use a brief reassuring phrase and help your child return to sleep. Starting a new game, long negotiation or a different response at every waking can prolong alertness.
What should you track for a week?
Note bedtime and time to fall asleep, naps, when and how long your child wakes, what helped, snoring, illness and daytime behavior. The goal is not a perfect sleep score but a clear pattern to discuss with your clinician or caregiver.
What can you do if fears are increasing?
Take the fear seriously while reassuring your child that they are safe. Talk briefly during the day, consider a night-light or familiar safe object, and review frightening content. At night, repeat the same short reassurance instead of giving a long explanation.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Frequent loud snoring, pauses in breathing, laboured breathing or marked daytime sleepiness.
- Waking with pain, fever, repeated vomiting, seizure-like movements, unusual confusion or other clear signs of illness.
- Sleep problems lasting weeks and clearly affecting the child’s or family’s daytime functioning.
