It is 1.40 a.m., and what comes from the children's room is not a little grumble but real crying. You comfort your child, settle them back down – and an hour later it starts all over again. After three nights like that, you are simply running on empty. The good news: when a child wakes up at night crying, there is usually no problem behind it, but a developmental phase – and that phase looks very different at eight months than at four years. This is why general sleep tips achieve little. It is far more effective to start from your child's age: what is typical right now and what actually helps.
The short answer: waking at night is normal between six months and six years – every child wakes briefly several times a night, and most simply fall asleep again. When real crying is involved, the cause is almost always age-related: separation anxiety and teething in the first year, developmental leaps in the second, growing autonomy between two and three, nightmares and night terrors between three and four, nursery topics and fear of the dark between four and six. What matters is less what you do than that you do it calmly, quietly and the same way every night.
- All children wake several times a night – that is part of normal sleep.
- Tell brief half-asleep calls apart from real crying: only the latter needs your response.
- The cause depends on age – from separation anxiety at around eight months to fear of the dark at nursery age.
- At night: wait briefly, little light, few words, always respond the same way.
- Seek medical advice for pain, night-time snoring with pauses in breathing, or a sudden change.
Why waking at night is part of normal sleep
Sleep runs in cycles. In young children one cycle lasts around 50 to 60 minutes, in adults about 90. At the end of each cycle there is a short phase close to the surface: your child turns over, mumbles, looks for a comfortable position. Adults do not notice it, because they have learned to settle themselves again with their eyes closed.
That very ability is still developing in young children. A child who at that moment cannot find the conditions they fell asleep in – their mother's arm, the bottle, a hand on their back – will call out. This is neither a setback nor a parenting mistake, but a question of maturity; how it changes over the months is described in the article Child wakes up at night.
A brief call or real crying – the crucial difference
The half-asleep call is short, irregular and fades by itself: 20 or 40 seconds of grumbling, turning over, then quiet. Rushing into the room and switching on the light at that moment turns a half-asleep child into a fully awake one.
Real crying builds up instead of fading, grows louder and more urgent and does not stop after two minutes. Behind it is something your child cannot solve alone – fear, pain, hunger, a full nappy, cold, a bad dream. This is where you belong, without hesitating.
Most parents can tell the difference after a few nights. Until then, one simple trick helps: count slowly to 60 before you get up – a good share of these situations resolve themselves within that minute.
Child wakes up at night crying: causes by age
The ages given are guide values: some topics appear earlier or later.
6 to 12 months: separation anxiety, teething, hunger
Sleep cycles are still maturing, and at around eight months a major developmental step is added: your child grasps that mum and dad continue to exist even when they are not in the room – and misses them all the more. This separation anxiety is a sign of secure attachment, but it makes nights temporarily harder. Add teething, a genuine need to feed and the first attempts to sit up while asleep.
For the first year, the official recommendations for safe baby sleep also apply: the baby sleeps on their back, in their own bed, but in the parents' bedroom. No loose blankets and no pillows – a sleeping bag replaces the duvet. Room temperature is ideally around 18 °C. If you are unsure, ask at your paediatric practice.
12 to 24 months: developmental leaps and the evening goodbye
Learning to walk, the first words, starting at the crèche or playgroup: in the second year so much happens during the day that the brain reworks it at night. Many children who slept peacefully at ten months suddenly wake up crying again. The evening also becomes harder – your child now understands that you are still awake after the goodnight kiss. What helps: a ritual of 20 to 30 minutes that runs the same way every evening, plus a calm goodbye signal.
2 to 3 years: autonomy, regression and a waking imagination
At two, your child discovers "no" – around the clock. At the same time, imagination becomes so strong that real and imagined events can get mixed up at night. Many families experience a clear sleep regression around the second birthday: the child wakes up crying, does not want to be alone, gets out of bed several times. Common triggers are a change of room, a house move, a new sibling or the start of potty training. Now predictability pays off: the same sequence, the same sentences, the same limits.
3 to 4 years: telling nightmares and night terrors apart
A night terror usually occurs one to three hours after falling asleep, coming out of deep sleep. The child screams, seems panicked, may have their eyes open – but is neither awake nor responsive. Comforting does not help, and neither does waking them; in the morning they remember nothing. The right approach: stay close, keep them safe, speak quietly, wait. Details in the article Night terrors in children.
Nightmares, by contrast, typically happen in the second half of the night, when dream phases get longer. The child wakes up properly, is responsive, seeks closeness and can often say what they dreamt. Here comforting is exactly right – how to work through it during the day without making it bigger is explained under Nightmares in children.
4 to 6 years: nursery, fear of the dark and staying dry
At nursery age, the night is used to process what occupied the day: an argument over the znüni snack, a new group, a house move. On top of that comes fear of the dark, which affects almost all children of this age at some point – not because something is missing, but because they now have enough imagination. A dimmed night light and an open door are not spoiling, but a pragmatic tool, as the article Fear of the dark shows. The second topic is the bladder: many children stay dry at night between four and six, others later – this is a matter of maturation and cannot be trained.
| Age | Typical cause | How to recognise it | What helps |
|---|---|---|---|
| 6–12 months | Separation anxiety, teething, hunger | Calms quickly as soon as you are in the room | Show yourself briefly, a hand on the back, safe sleep environment |
| 12–24 months | Developmental leaps, walking, language | In phases, over 2 to 4 weeks | Consistent bedtime ritual, clear goodbye signal, patience |
| 2–3 years | Autonomy phase, sleep regression, imagination | Child calls out, negotiates, gets up, wants to decide | Predictable sequence, friendly limits |
| 3–4 years | Nightmare or night terror | 2nd half of the night and responsive = nightmare; 1st half and unresponsive = night terror | Nightmare: comfort, let them talk. Night terror: keep safe, do not wake |
| 4–6 years | Nursery topics, fear of the dark, bladder | Child can name what is on their mind | Talk about it by day, night light, open door, no pressure |
The first few minutes: how to respond at night
What you do in the first five minutes often decides whether the night continues after ten minutes or only after an hour and a half.
- Wait briefly. Count slowly to 60. If the noise fades, stay in bed.
- Go in quietly, little light. No ceiling light, no phone screen – bright light signals "morning".
- Always the same sentence. For example: "I'm here. It's night-time. You can keep sleeping." Same wording, every night.
- Check physical causes. Nappy, temperature at the neck rather than the hands, fever, a cough, a twisted sleeping bag.
- No long conversations. There is no negotiating at night – anything substantial waits until morning.
- Do not establish new habits. Whatever you do three nights in a row, your child will expect on the fourth.
Comforting or waking up – a fine line
Comforting means giving security so your child can find their way back to sleep. Waking up means giving the brain so many stimuli that it leaves night mode.
What works as comfort: closeness, a calm hand on the back, a quiet, monotone sentence, dimmed light. What works as waking up: carrying your child around the room, switching on the light, asking questions ("What's wrong? Did you have a bad dream?"), going to the kitchen, offering food, switching on a screen. If your child is more awake after being comforted than before, it is usually down to one of these points.
What works during the day – more than any night-time strategy
Rhythm. Consistent waking, nap and bedtimes, at weekends too, with no more than 30 to 45 minutes' variation. An overtired child sleeps more restlessly, not better.
Separation games. Peekaboo, hide and seek, short separations with a clear announcement and a reliable return practise exactly the experience needed at night.
Bedtime ritual. 20 to 30 minutes, always in the same order, in the same places every evening.
Reading aloud. Ten minutes lower tension and offer an occasion to talk about topics that come back at night. Books in which a character is afraid and endures it help more at nursery age than any reassurance.
Review of the day. Five minutes before lights out: what was lovely today, what was rubbish? A child who has talked in the evening has less to process at night.
Common mistakes
- Responding too quickly. Going into the room at the first sound interrupts independent settling.
- Trying something different every night. Three approaches in five nights work like none at all – stick with one route for two weeks.
- Trying to parent at night. At three in the morning nobody can learn. Rules are discussed by day.
- Dropping the nap too early. Between two and four, many children still need a rest period.
- A late dinner and screen time right before bed. Both delay falling asleep.

Parents at their limit: fair nights and looking after yourselves
Interrupted sleep over weeks affects mood, patience and reaction times – that is not a question of character. Getting up three times a night costs less in hours than in sleep quality. So divide the nights deliberately: fixed shifts rather than "whoever wakes up first". One person takes over until two o'clock, the other afterwards; at the weekend you take turns having a lie-in in another room. In flats with thin walls it also helps to let go of the expectation that your child must be quiet immediately. And if it all gets too much: every Swiss municipality has a parent and child counselling service, usually free of charge and intended for exactly these questions.
When to seek medical advice
Most of these phases pass by themselves. In these situations, however, raise the topic actively at your paediatric practice:
- Your child snores regularly at night or has pauses in breathing – this should always be investigated.
- The crying comes with signs of pain.
- The pattern has changed suddenly and markedly, with no recognisable reason.
- Your child is noticeably tired or irritable during the day despite enough hours in bed.
- The family's exhaustion persists.
Frequently asked questions about crying at night
At what age do children sleep through the night?
There is no age at which all children sleep through. Brief night-time waking phases remain into adulthood, they simply stop being noticed. Many children reach longer stretches between two and three years, some earlier, others later.
Should I pick my child up straight away at night?
With real crying that builds up, go to them without hesitating. Picking them up is not always necessary: often closeness, a hand on the back and a calm voice are enough. With grumbling in half-sleep it is better to wait a minute.
How do I tell a night terror from a nightmare?
By the timing and the responsiveness. A night terror usually happens one to three hours after falling asleep, the child is not responsive and remembers nothing in the morning. A nightmare happens more in the second half of the night: the child wakes up properly, seeks closeness and can often say what they dreamt.
Can my child still drink at night?
A sip of water is unproblematic – put the cup within reach by the bed. Milk or sweetened drinks at night are unfavourable, for the teeth and because they quickly become a fixed habit. For babies under one year, discuss night-time needs at your paediatric practice.
What should I do if the crying comes at the same time every night?
A very regular time in the first half of the night often suggests a night terror. Keep a short log for a week with the time, duration and behaviour, and discuss a stable pattern at your paediatric practice.
When should we seek medical advice?
If your child snores at night or has pauses in breathing, if pain could be involved, if sleep changes suddenly for no apparent reason, if your child is noticeably tired and irritable during the day, or if the family's exhaustion persists.
