What age should my toddler move to a bed?

Most children move between 18 months and 3 years, but there is no single right age. The main reasons to make the move are safety (your toddler is climbing out of the cot and at risk of falling) or practical need (a new sibling needs the cot). If neither of those applies, leaving your toddler in the cot until they are 3 or even a little older is completely normal and often leads to a smoother transition because they are more cognitively ready to understand staying in bed.

My toddler is climbing out of the cot — what should I do?

Climbing out of the cot is the main safety signal that the cot is no longer safe. Once your toddler can consistently climb out, the cot side is no longer a reliable barrier and the risk of a fall is real. At this point, moving to a low bed (or a floor mattress) removes the height risk. Before you make the move, also check whether the cot mattress can go down further, and make sure your toddler is not being motivated to climb by putting them down before they are tired enough.

How do I stop my toddler getting out of bed at night?

Getting out of bed repeatedly after the move is almost universal. The most important thing is to be calm, brief and completely consistent. Walk your toddler back to bed with minimal engagement: no lectures, no conversation, just a quiet 'back to bed' and a calm walkback. Two techniques that many families find helpful are the hall pass (give your toddler one token per night to 'spend' on one approved reason to get up) and a toddler clock such as a Gro Clock, which uses a light to show when it is morning and when it is still sleep time. Both take a week or two to work but can make a big difference once your toddler understands the rules.

What type of bed is best for a toddler?

There is no single best option, but the safest is whichever is lowest to the ground. A mattress on the floor has no fall risk at all and works well, especially in the early months of the transition. A toddler bed with side rails uses the same mattress as the cot, is low, and has built-in rails, which is convenient and reassuring for many children. A standard single bed with a bed guard is also fine and avoids buying a transitional bed you will outgrow quickly. Whichever you choose, make sure the mattress is firm and fits snugly so there is no gap a child could get trapped in.

Will the transition affect my toddler's sleep?

It often does, at least temporarily. Many toddlers experience a period of disrupted sleep after moving to a bed, particularly in the first few weeks. This is very common and does not mean you made a mistake. Keeping the same bedtime routine, the same bedtime, and responding consistently to getting-out-of-bed behaviour is the most effective way to shorten the disruption. Most families see nights settle down within two to four weeks, though some regression at later points (illness, stress, developmental leaps) is normal.

What are the safety rules for a toddler bed?

Once your toddler is mobile at night, the whole bedroom becomes the sleep environment. Key safety steps are: use a low bed or mattress on the floor to minimise fall height; fit a stair gate at the bedroom door or at the top of the stairs so your toddler cannot roam the house unsupervised at night; secure all furniture to the wall (IKEA anti-tip straps and equivalent brackets are widely available and simple to fit); cover electrical outlets; and remove any items your toddler could use to climb onto furniture or windowsills. Check the room from a toddler's-eye-view before the first night.

Moving from cot to toddler bed: when, how and what to expect

18 to 36 months · Sleep · Updated July 2026 · All articles

There is no deadline for moving your toddler out of the cot. Plenty of three-year-olds sleep perfectly well in theirs, and that is absolutely fine. The transition is worth making when there is a genuine reason to make it, not just because your toddler has reached a certain age. This article walks you through the real signals to watch for, how to prepare when the time comes, and how to handle the disruption that almost always follows.

There is no rush

The cot is not just a place to sleep. For a toddler, it provides containment: a predictable, enclosed space that signals sleep and helps prevent them from getting up and roaming the house during the night. Moving to a bed removes that boundary entirely, handing your toddler both freedom and responsibility at a stage when their impulse control is still very much in development.

Toddlers under about 2.5 to 3 years typically lack the cognitive maturity to understand and consistently follow a rule like "stay in bed until morning." That does not mean earlier transitions are impossible, but it does mean they are more likely to come with weeks of repeated bedtime curtain calls and disrupted nights. Many families who move early regret it. If your toddler is sleeping well in the cot and there is no safety concern or practical reason to change, the single most useful thing you can do is wait.

When it is time to make the move: signs to look for

They are climbing out of the cot

This is the main safety signal. Once your toddler can reliably haul themselves over the cot rail, the cot is no longer a safe environment: the risk of a fall onto a hard floor is real and has caused serious injuries. When climbing out becomes consistent, moving to a low bed eliminates the height risk. Before you make the move, it is worth checking whether the cot mattress can go down to its lowest position and whether your toddler is climbing because they are not quite tired enough when you put them down. But if they are getting out routinely, the cot has done its job.

A new baby needs the cot

A practical and very common reason. If this applies, try to make the move at least six to eight weeks before the new baby arrives so your toddler does not feel pushed out. If your toddler is under 2, consider borrowing or buying a second cot rather than moving them too early. The disruption of a new sibling plus a bed transition at the same time can be a lot for a young toddler to manage.

They are showing interest in a big bed

Some toddlers start asking about "a proper bed" or showing excitement when they see one. Enthusiasm is not sufficient on its own, but if your toddler is old enough (closer to 3) and genuinely keen, their buy-in can make the transition go more smoothly. Curiosity plus readiness is a good combination.

They are working towards toilet training

Once your toddler is getting more confident with the toilet, being able to get out of bed independently to go to the bathroom at night becomes useful. A cot makes that impossible. If toilet training is well established (not just starting), this can be a sensible moment to make the move.

Why not to rush: what the cot is actually doing

Paediatric sleep researchers note that the cot's value is not only in keeping the child safe from falls. It also acts as a consistent physical boundary that supports a toddler's ability to stay in a sleep space. Once that boundary is gone, many toddlers will test what the rules are, repeatedly and for several weeks, before accepting that staying in bed is simply what happens at night.

Children under 2 particularly lack the executive function needed to hold a rule in mind and override the impulse to get up and find you. Moving a child of 18 months to a bed because their older sibling had one at that age, or because you feel they "should" be in one by now, is likely to be harder for everyone than waiting until they are closer to 3. The NHS and the American Academy of Pediatrics both note that there is no set age recommendation and that most children are ready somewhere between 18 months and 3 years, with the older end of that range often meaning a smoother experience.

Equally, do not move at a disruptive time. Starting potty training, moving house, a new sibling arriving, or a major change to your routine all add stress that can make the bed transition harder. Pick a period that is as calm and settled as possible.

Preparing for the move

Involve your toddler. Children this age respond well to feeling like part of a decision rather than having it happen to them. Talk about the bed before it arrives. Let them come to the shop or look at pictures online and choose something, even if it is just the colour of the bedding. Let them help put the sheets on. A few days of anticipation can shift the frame from "something is changing" to "something exciting is happening."

Keep the rest of the bedroom exactly the same. The same nightlight, the same white noise machine if you use one, the same comforter or soft toy in the same place. Everything familiar helps.

If you still have the cot assembled in the same room for a short transitional period, that is fine, but try not to let it become a fallback. Moving back into the cot once the bed is in place tends to confuse rather than reassure. If your toddler genuinely cannot manage in the bed yet, it is better to acknowledge that and plan the move for a few weeks later.

Choosing a bed

Mattress on the floor

The safest option in terms of fall risk. Place the cot mattress or a new single mattress directly on the floor and your toddler has nowhere to fall. This works very well as an initial step and is particularly useful if your toddler is on the younger or more mobile end of the range. Some families keep the floor mattress for months before moving it onto a frame.

Toddler bed with rails

Toddler beds are designed to use the same mattress as a cot and are low to the ground. They usually come with partial side rails that prevent rolling out while still letting your toddler get in and out easily. The rail height tends to be lower than a full cot side, so there is still a small fall distance if your toddler rolls, but it is modest. The main drawback is cost: a toddler bed is a transitional purchase that your child will outgrow within a few years.

Single bed with a bed guard

If you want to skip the toddler bed stage, a single bed with a fitted bed guard along one side is a practical and economical choice. Make sure the guard fits properly and has no gap between it and the mattress that a small child could slip into. A low divan-style base, rather than one with a high frame and legs, keeps the overall height manageable.

Whichever option you choose, the mattress should be firm and fit snugly into the frame with no gap at the sides. A mattress that moves around or has wide gaps at the edges is a hazard for a young child.

Making the bedroom safe

The most important thing to understand is that once your toddler is in a bed, they can leave the room at night. The bedroom, the landing, and the stairs all become part of their accessible space unless you take steps to contain it. Do a safety review before the first night in the new bed.

Stair gate: fit a gate at the bedroom door or at the top of the stairs. A toddler finding their way to the stairs in the dark, half asleep, is a serious risk. Many families keep the stair gate in place until age 4 or 5.
Furniture anti-tip straps: secure all chests of drawers, bookshelves and wardrobes to the wall. IKEA and most major furniture brands include anti-tip brackets or sell them separately. An unsecured chest of drawers can tip onto a child if they use a drawer as a step to climb.
Outlet covers: check that all electrical outlets in the room are covered or out of reach.
Climbable furniture: remove chairs, toy boxes or anything your toddler could use to climb onto a windowsill or high piece of furniture, and fit window restrictors if windows are reachable.
Loose items: clear the floor of anything that could cause a trip in the dark, including toys with sharp edges or strings.

The Lullaby Trust recommends checking that children's sleep environments remain safe as they develop, recognising that the hazards change as toddlers become more mobile and more curious.

The transition: what to actually do

The single most protective thing you can do is keep the bedtime routine exactly the same as it was in the cot days. Same time, same sequence. Bath, into pyjamas, teeth, a story or two, lights down, a short cuddle, then into bed. The routine is the signal that sleep is coming, and toddlers who have a predictable, calming routine settle more easily regardless of where they are sleeping.

Put your toddler into the bed in the same way you would have put them into the cot: drowsy but not yet asleep if possible, so they go to sleep in the space they will wake up in. If your toddler has always needed you to stay until they are fully asleep, the bed transition is likely to surface that dependency more visibly, because now they can come and find you. It may be worth working on independent settling at the same time, or accepting that it will take longer to get out of the room each night for a few weeks.

Keep your response at bedtime warm but brief. Long drawn-out goodbyes give your toddler more opportunity to negotiate. Say goodnight, say you love them, and leave. If they call out, respond calmly and minimally from outside the door for the first few nights before gradually not responding at all.

When they keep getting out of bed

Getting out of bed is almost universal in the first weeks and often continues for longer. It is important not to treat it as misbehaviour: your toddler is testing a new situation, which is developmentally normal. What matters is your consistency in response, because inconsistency (sometimes going back, sometimes not; sometimes engaging, sometimes not) teaches your toddler that persistence pays off.

The most effective approach is calm, quiet and boring. Walk your toddler back to bed with minimal interaction. No lectures, no additional stories, no discussion about why they need to stay in bed. A brief "it's bedtime, back to bed" and a tuck-in is enough. Repeat as many times as needed. This is relentless at first and then, usually within one to three weeks, the behaviour fades because it stops working.

The hall pass technique

The hall pass is a technique that many families find helpful for toddlers who are old enough to understand a simple rule (roughly 2.5 and up). Give your toddler one physical token at bedtime, a small card, a tile, or a peg. They are allowed to use it once to get up for one approved reason: a drink of water, a cuddle, a toilet trip. When the token is used, it is gone and there are no more trips out of bed. The technique gives your toddler a sense of agency and a legitimate outlet, which often reduces the overall number of exits. Return the token the next morning and start again.

A toddler clock

A toddler-friendly wake-up clock, such as a Gro Clock or similar, shows a visual cue for "still sleep time" (often a night scene or a particular colour) and a different cue for "morning" (a sun, a different colour). Because toddlers cannot read a clock face, these devices give them something concrete to refer to when they wake up. Most families find it takes a week or two for the concept to really land, but it can be very effective for early waking as well as getting out of bed at night. Choose a consistent morning time and stick to it.

Regression after the move: what to expect

Many toddlers experience a genuine sleep regression in the weeks following the move to a bed. They may wake more in the night, take longer to settle, or start waking very early. This does not mean the transition was a mistake. It means your toddler's sleep is adjusting to a new situation, and their nervous system needs time to catch up.

The most useful thing you can do during a regression is stay consistent. Keep the routine, keep the response to getting-out-of-bed behaviour consistent, and avoid introducing new sleep associations (such as lying with your toddler until they fall asleep) that you will then need to remove again. Most regressions resolve within two to four weeks if the routine and boundaries remain steady. If your toddler is still significantly more disrupted after four to six weeks, it is worth a conversation with your health visitor to rule out other causes.

Naps in the toddler bed

Daytime naps in the new bed can be harder to manage than night sleep, particularly in the first few weeks. Your toddler has less natural sleep pressure during the day and more motivation to play now that they can get up freely. Some toddlers drop their nap around this time, sometimes because the transition disrupts the nap routine enough that it disappears, and sometimes simply because they are developmentally ready to drop it (most children stop napping between 2.5 and 4 years).

If you want to preserve the nap, treat it with the same structure as the night routine: a short, consistent wind-down, the same cue (curtains closed, white noise on), and a clear end time so your toddler is not in the bed indefinitely. If the nap consistently takes more than 30 minutes to happen, or stops happening altogether despite your efforts, it may be a signal that your toddler is ready to replace it with a quiet time instead: 30 to 45 minutes in their room with books or soft toys, without screens.
