Toddler doesn't sleep through: Why it happens and what may help

Toddler doesn't sleep through the night: What does sleeping through actually mean?

If your toddler calls for you two, three or five times a night, the night understandably feels anything but uninterrupted. Yet good child sleep does not necessarily mean that a child never wakes briefly between bedtime and morning. Children and adults move through different sleep phases during the night and may briefly wake between them.

The key difference is often what happens next: does your child turn over and go back to sleep, or do they become fully awake, call for you and need longer support? How often does it happen? And how is your child – and your family – the next day? Our guide When do babies sleep through the night? explains in more detail how “sleeping through” can be defined and how this ability develops.

Night waking on its own is not yet a sleep disorder. Frequency, duration, getting back to sleep and the level of strain on child and family matter more.

The overview below helps you distinguish different situations. It is not a diagnosis, but it shows what to look at in your family's sleep pattern.

If your child is still in the first year of life, expectations around sleep are partly different. Our guide Baby won't sleep is the better starting point for that age.

Why toddlers keep waking at night

Sleeping through does not depend only on what happens at night. Development, daily routine, sleep need, emotions and habits all interact. There is therefore rarely one single cause that applies to every child.

Development and independence can be busy at night too

A huge amount happens during the toddler years. Walking, talking, understanding, making choices and testing boundaries all change everyday life. A child can look very independent during the day and still need a great deal of reassurance at night. New skills and impressions have to be processed, and previously calmer nights can temporarily become more unsettled again.

Separation and changes can increase the need for closeness

Starting nursery, moving house, a new sibling, travel or other changes can increase the need for security. Even without a major event, toddlers go through phases when separation from caregivers feels harder. This may only become obvious at bedtime or during the night when your child realises you are not immediately beside them.

Sleep needs change

As children get older, they generally need less sleep overall. At the same time, there are clear individual differences. Toddlers between one and two years often fall roughly within 11 to 14 hours of sleep over 24 hours; for children aged three to five, around 10 to 13 hours is a common orientation. These figures are not targets. You can find more detail in our sleep duration table for children.

If your child regularly is not tired for a long time in the evening or has long awake periods at night, too much time may simply be allocated for sleep. On the other hand, overtiredness can also make falling asleep and the night more unsettled.

Naps change sleep pressure

Many toddlers still need a daytime nap. At some point it becomes shorter, shifts or disappears – and this transition rarely happens from one day to the next. A long or very late nap can mean your child is not tired enough in the evening. If daytime sleep is removed too early, however, your child may become overtired in the afternoon and also settle less well.

Falling-asleep support is often sought again at night

If your child usually falls asleep while holding your hand, being carried, breastfeeding, having a bottle or with you directly beside them, they may ask for the same familiar situation again when they wake at night. That does not automatically make the sleep aid “wrong”. What matters is whether it still works for your family or whether you want to change something.

Fears and vivid dreams become more important

As imagination develops, darkness, noises or imaginary figures can suddenly feel more frightening. Nightmares also become more relevant in the toddler years. This is different from a night terror: during a night terror, a child may look extremely distressed but is not properly awake and can often barely be spoken to or comforted.

Physical discomfort can disturb sleep

If a child usually sleeps calmly and suddenly wakes again and again, teething, an infection, pain, coughing or other physical discomfort may also play a role. On those nights, changing a sleep habit is not the priority; helping your child feel well again is.

Seven steps when your toddler does not sleep through

When everyone is exhausted, it is tempting to change bedtime, the nap, falling-asleep support and your night-time response all at once. That makes it hard to see what actually helps. A step-by-step approach is more useful.

1. Observe the pattern: When does your child fall asleep, when do they wake and how long does it take them to get back to sleep?
2. Look at total sleep: Add night sleep and naps and check whether the planned bedtime fits your child's current sleep need.
3. Include the nap: If your child lies awake for a long time in the evening, first look at the timing and length of the nap instead of removing it completely straight away.
4. Make the evening predictable: A manageable sequence of dinner, quiet activity, toothbrushing, getting changed, a story or song signals that the day is ending.
5. Respond similarly at night: Low light, little activity and a calm familiar response make it clear that it is still night.
6. Change one habit at a time: If you want to reduce falling-asleep support, for example, keep bedtime and other familiar routines as stable as possible at first.
7. Observe for several days: A change does not have to work on the first night. Only a pattern over several days shows whether you are moving in the right direction.

The goal is not to make your child stop needing help at night as quickly as possible. A more useful goal is a sleep situation that matches their development and remains manageable for your family.

Nap: Shorten it, move it or keep it?

The nap is one of the most common factors parents look at with toddlers – and one where it is easy to react too quickly. Difficulty falling asleep at bedtime or waking at night does not automatically mean your child no longer needs a nap.

Look at the whole day instead. If your child sleeps for a long time and late at midday and is regularly wide awake in the evening, it can make sense to offer the nap earlier or shorten it gently. If, without a nap, your child is already very exhausted or irritable by late afternoon or unexpectedly falls asleep in the car, stopping it completely may still be too early.

The transition can be inconsistent. Some children still nap on active days and manage without daytime sleep on other days. A rigid rule is less useful than looking at tiredness, evening behaviour and total sleep duration.

If your child only goes back to sleep with you

Many toddlers look for exactly the support at night that helped them fall asleep in the evening. That may be your hand, body contact, breastfeeding, carrying or simply your presence. As long as this works for your family, it does not automatically need to become a problem.

If the situation is exhausting you night after night, you are allowed to change it. That does not mean suddenly withdrawing closeness. You can alter the support gradually: from carrying to cuddling, from cuddling to hand-holding, or from constant presence to short reliable check-ins. The right steps depend on your existing routine and your child's age.

It can also help if another familiar caregiver takes over some bedtime or night situations. A child can develop different ways of falling asleep with different people without one of them being the only “correct” way.

What may help when your child wakes at night

No one needs a complicated programme in the middle of the night. The clearer you are about how you want to respond to ordinary waking, the easier it is for the sequence to remain predictable even when you are tired.

• Keep the light as dim as possible and avoid unnecessary activity.
• Speak calmly and briefly instead of turning the night into a new time for play or conversation.
• Give your child the closeness they need to settle without automatically adding more and more sleep aids.
• If your child is thirsty, water is the simplest option.
• After a nightmare your child needs orientation and comfort; during a night terror they are often not truly awake.
• If your child seems ill or in pain, their physical wellbeing comes before any sleep routine.

Consistency does not mean being harsh. It mainly means that your child roughly knows what happens at night and that you do not try a completely new method every night.

Evening routine and sleep environment support the night

An evening routine cannot guarantee sleeping through. It can, however, create a reliable transition between an active day and the night. It is particularly helpful when the daytime routine also includes enough movement, daylight and calmer periods.

Try to reduce exciting activities towards the evening. Screens can make winding down harder and should not play a role just before bedtime for young children. Caffeinated drinks also do not belong in a toddler's everyday diet.

The bedroom should be calm, rather dark and not overheated. When your toddler grows out of their previous baby cot, an age-appropriate sleep space also becomes important. One flexible option is the babybay® All in One with a 70 × 140 cm sleep surface: it can be used as a classic cot and children's bed, while the open side also allows it to be used as a bedside crib directly next to the parents' bed. Especially if your child still seeks a lot of closeness at night, this can be one way to combine their own sleep space with immediate proximity. A different bed is not, however, a treatment for frequent night waking – the whole sleep pattern still matters.

Sleep diary: Look for patterns instead of individual bad nights

When night waking is frequent, a sleep diary can be surprisingly useful. After several exhausting weeks, the nights can easily blur together and it is understandable to feel as if your child is “always awake”.

For around two to three weeks, roughly note when your child falls asleep and gets up, when and how long they nap, how often they are fully awake at night and approximately how long it takes to fall asleep again. Add special events such as illness, nursery days, travel or unusually exciting days.

This may show, for example, whether long awake periods mainly happen after a late nap or whether the problem really appears independently of the daily routine. It also gives you a useful basis if you want to discuss the issue professionally.

When frequent waking may be more than a difficult phase

Because this search topic specifically describes a persistent sleep problem, a professional assessment can make sense. Not every unsettled night needs medical evaluation. If a pattern occurs very frequently over weeks or additional concerns appear, it is worth looking more closely.

As an orientation for a pronounced sleep-maintenance problem after the first birthday, one relevant pattern is waking several times on many nights for at least around a month, staying awake for longer periods and regularly needing parental help to fall asleep again. How strongly the child and family are affected always remains important too.

You should seek paediatric advice in particular if your child regularly snores unusually loudly, has pauses in breathing or their breathing during sleep seems unusual, if they are clearly and persistently tired or impaired during the day, if physical symptoms may be behind the waking, or if the sleep situation is placing a strong long-term strain on your family.

Do not give a toddler sleeping medicines, melatonin or other preparations on your own initiative. With persistent sleep problems, clarifying the cause comes before any possible medication.

Conclusion: Sleeping through develops – and nights can still become easier

A toddler waking at night does not automatically mean something is wrong. At the same time, you do not simply have to accept permanently exhausting nights. The key is understanding your actual pattern: How much does your child sleep overall, does the nap still fit, what support do they need to fall asleep and what has changed in everyday life?

Start with small understandable adjustments and give them time. If your child is developing well during the day and you can cope with the night-time waking, not every interruption has to be eliminated. If the nights become a persistent problem or concerning accompanying signs appear, professional support is the appropriate next step.
