How to Get Your Toddler to Sleep Through the Night

If your toddler wakes every night somewhere between 1am and 3am, you are not doing anything wrong and you are not the only one awake. Night waking is close to universal in the toddler years, and there is a boring, hopeful truth at the centre of it: toddlers wake because of how sleep works, and they can learn to settle back down because of how habits work.

Why toddlers wake at night

Everyone surfaces between sleep cycles several times a night. Adults roll over and forget it ever happened. A toddler surfaces, notices the room is dark and you are gone, and does the only sensible thing available: shouts for the person who fixes everything.

The waking is not the problem. Needing you to get back to sleep is the part you can change.

A few things make it worse. Separation anxiety peaks in the toddler years, so being alone at 2am feels bigger to them than it did at ten months. Big changes ripple into the night: a new sibling, a new bed, potty training, starting nursery. And overtiredness is a trap that catches almost everyone, because a toddler who goes to bed too late does not sleep deeper. They sleep worse, with more waking, and often earlier mornings. If there is still a daytime nap, its timing matters too. A long nap that finishes at 4pm quietly steals the pressure a child needs to fall asleep at 7.

The night is won in the evening

A consistent wind-down is the single highest-value thing you can change this week. Same steps, same order, every night: bath, pyjamas, teeth, two books, a song, bed. Twenty to thirty minutes, lights low, voices lower. The routine is not magic. The repetition is. A toddler who knows exactly what happens next has nothing left to negotiate.

For most toddlers, a bedtime somewhere between 6.30 and 8pm works. The NHS puts total sleep needs at roughly 11 to 14 hours in every 24 for one to two year olds, including the nap, and 10 to 13 hours for three to five year olds. Work backwards from their wake-up time and their nap, and put bedtime where the maths says, not where the evening battle has slowly pushed it.

Screens off an hour before bed. And watch for the overtired second wind: a toddler bouncing off the walls at 7.45 is often not under-tired but past it.

The 2am response

Boring is the strategy. Go in calm, keep the light low, use the same few words every time, and keep it short. Pick a script and stick to it: "It's night-time. You're safe. Lie down. I love you. See you in the morning."

Then the rule that saves families months: only offer at 2am what you are happy to keep offering at 2am. A one-off milk feed to buy silence becomes a nightly milk feed within the week. Toddlers are excellent scientists. Whatever worked last night will be tested tonight.

If they end up in your bed and you would rather they did not, walk them back each time, calmly, however many times it takes, with the same dull sentence. If sharing a bed works for your family and everyone actually sleeps, that is a choice, not a failure. The only wrong setup is the one nobody chose and nobody is sleeping through.

When only one parent will do

In a lot of houses the 2am call is addressed to one parent by name, and the other parent's arrival is treated as an insult. It is normal, it is a phase, and it is fixable, but only if both of you respond the same way.

Agree the script and the steps together, then swap in the less-preferred parent gradually: they lead the settle while the preferred parent stands at the door, then waits on the landing, then stays in bed. Expect protest for a few nights. The prize is a household where either of you can run the night shift, which is the difference between one exhausted parent and two functioning ones.

Hold the line for two weeks

Whatever approach you pick, hold it steady for two weeks before you judge it. Nights often get louder before they get quieter, because a toddler's first response to a changed rule is to test it harder.

Keep a simple sleep diary and compare weeks, not nights. Memory at 3am is a liar. Week-on-week, on paper, you will usually find things are improving sooner than they feel like they are.

When to talk to a doctor instead

None of this applies if something is wrong. Loud snoring, gasping or pauses in breathing, ear-pulling or other signs of pain, or a sudden collapse in sleep from a child who previously slept well are all reasons to see your GP or health visitor rather than adjust a routine.

Quick answers

How long should a toddler sleep at night?

Most guidance, including the NHS, lands at around 11 to 14 hours per 24 for one to two year olds and 10 to 13 for three to five year olds, naps included. In practice that is usually 10 to 12 hours at night plus whatever the nap contributes.

Is this a sleep regression?

If sleep fell apart suddenly around a burst of development or a big life change, quite possibly. Regressions are real and they pass, faster when the routine stays steady through them. We cover the full timeline in our sleep regressions guide.

Should we drop the nap?

Most children drop it somewhere between two and four. If bedtime has become a 9pm fight, the nap may be too long or too late. Trim it or move it earlier before you cut it entirely.
