Most parents don't spend much time thinking about the cot until their little ones start trying to climb out of it. One night they're happily tucked in, and the next you're wondering how they suddenly learned to get a leg over the rail.
That little escape attempt is often what starts the conversation about a proper bed.
The change itself sounds straightforward, but anyone who's been through it knows bedtime can become a little unpredictable. A child who once settled without a fuss may suddenly need another story, another drink, or a reason to come out of their room.
It doesn't mean you've done anything wrong. A cot gives a young child a very clear boundary around their sleeping space. Once that boundary disappears, they need time to understand the new arrangement.
When Should a Child Move from a Cot to a Bed?
There isn't a particular birthday when every child should leave the cot. Some babies are happy sleeping there for quite a while, while others seem ready for a bed much sooner. Safety tends to be a more useful guide than age.
There are other signs worth noticing too. Your little one’s might be interested in a sibling's bed, be asking for one of their own, or need more freedom at night because toilet training has started. If they're becoming cramped in the cot, that is another practical reason for considering a change.

Signs Your Child May Be Ready
Look at what is happening day to day rather than trying to match a particular age. A child who can follow simple bedtime instructions, climb safely, and understand that they need to stay in bed has some of the skills that make the change easier. You might also notice them talking about having a "big bed" or wanting to sleep like an older brother or sister. That interest can be useful because the move feels less like something being imposed on them.

When Waiting Makes More Sense
Sometimes the timing is simply not ideal. A new baby, a house move, starting nursery, or another major change can leave a toddler with plenty of new things to process already. If the cot is still safe, there is nothing wrong with waiting for a calmer stretch. You don't need to remove another familiar part of the child's routine just because they have reached a certain age. When climbing out has become a safety issue, though, waiting is a different matter. At that point, the sleeping arrangement needs attention.
How Can You Prepare Your Child for the New Bed?
A toddler doesn't need a long explanation about why they're moving beds. They usually respond better when the new arrangement becomes familiar before the first night.
If possible, let your child see the bed during the day. Sit on it together. Let them choose between two sets of sheets or decide where their favorite teddy should sit. These are small choices, but they give the child some ownership over what is happening.

Keep the Familiar Parts of Bedtime
There is no reason to replace everything at once.
If bath time usually comes before pyjamas, keep it that way. If there is a particular story every night, keep reading it. The same night-light, comforter or soft toy can provide a familiar point of reference when the bed itself is new. This is one of those situations where keeping things ordinary can help more than buying lots of new sleep products.
-
Let the New Bed Become Familiar First
Some toddlers are happy to sleep in the new bed straight away. Others prefer to get used to it first.
You could let your child climb onto it during the day, read a story there or have an afternoon nap in the new sleeping space. There is no rule saying the first introduction has to happen at bedtime. A few quiet days around the new bed may be enough for some children. Others will need longer.
What Should You Check Before the First Night?
Once a toddler can leave their bed, the whole bedroom becomes part of the sleeping environment.
Take a look around from their height. Things that were previously out of reach from the cot may suddenly be accessible. Check windows, blinds, cords, drawers, furniture, and anything small enough to be picked up and swallowed. Tall or unstable furniture should be secured where necessary. The bed itself should also suit your child's age and the room. A lower sleeping surface can make getting in and out less intimidating, particularly during the first few weeks.
What About Blankets and Other Bedding?
A new bed can be tempting to fill with cushions, throws, and soft bedding, especially when you're trying to make it look cozy. For a young child, however, more bedding isn't automatically better.
If you're considering a child weighted blanket, check the recommended age, size, weight, and usage information before buying or using one. Weighted bedding isn't suitable for every young child, and it should never be treated as a replacement for basic sleep safety.
What If Your Child Keeps Getting Out of Bed?
This is usually where the real work begins.
Your toddler has spent years sleeping behind cot rails. Now there is nothing stopping them from walking straight out of the bedroom, and naturally, some children want to see what happens when they do.
The first few attempts might even be funny. By the tenth trip back to bed, they probably won't be.
Keep your response calm and fairly uneventful. Walk them back, settle them, and use the same simple message each time. Long conversations can accidentally turn getting out of bed into part of the evening entertainment.
-
Don't Turn Bedtime into a Negotiation
Once a child realizes that getting out leads to another story, a snack, or ten minutes of conversation, they have a pretty good reason to keep trying.
That doesn't mean you need to be stern. It simply helps when bedtime remains bedtime. A short reminder, a quick tuck-in, and the same response each time can be enough. It may take several nights before your toddler realizes that leaving the room isn't going to change what happens next.
-
Keep the Evening Routine Much the Same
During this stage, familiar routines are useful.
Bath, pyjamas, teeth, story, and bed might already be part of your evening. There is no need to create a complicated new sleep program because the cot has gone. If something isn't working, make one change at a time. Otherwise, it becomes difficult to tell what is actually helping.
What If Your Child Feels Nervous in the New Bed?
Not every toddler sees a bigger bed as exciting. Some miss the enclosed feeling of the cot, particularly at night when the room is dark and everything feels different. Rather than assuming they're simply refusing to sleep, ask what feels wrong. Your child may be able to tell you that the room feels too dark, the mattress feels strange, or they want their old blanket.
For an older child who is already suitable for weighted bedding, Auteeze also has information about whether a therapy weighted blanket may be useful as part of a calming bedtime routine. Always check the product guidance and age suitability first.
Should You Go Back to the Cot?
After a string of difficult nights, it is understandable to wonder whether you've moved too soon.
If the cot is still safe and there wasn't a particular reason for making the change, some families choose to pause and try again later. There is nothing inherently wrong with that. Instead, look at what is making the new bed difficult. Sometimes a lower bed, a different position in the room or a more familiar bedtime routine can make the adjustment easier.
How Long Does It Take to Settle?
This is the part nobody can give you an exact answer for.
Some children barely notice the change. Others need a couple of weeks before the new routine feels normal. You might have three good nights followed by one where your toddler suddenly starts appearing beside your bed again.
That doesn't necessarily mean you've gone backwards.
Sleep can be affected by all sorts of things at this age, including illness, developmental changes, toilet training, and ordinary childhood worries. One difficult night doesn't undo the progress you've already made. What matters is what happens most of the time. Keep the room safe, keep bedtime familiar, and respond consistently when your child gets out.
Final Thoughts
The move from a cot to a bed is one of those milestones that looks very simple until you're standing in the hallway for the fifth time at 10 p.m.
Give your child some involvement in the change, keep familiar parts of the evening in place, and don't expect everything to settle on the first night. A few unsettled evenings are part of learning a new routine.
FAQs
1. When is the right time to move a child from a cot to a bed?
There isn't one perfect age for every child. Some toddlers are ready earlier than others. Instead of focusing only on their age, look at whether they can manage the change and whether their current cot is still safe for them.
2. Does climbing out of the cot mean my child needs a bed?
It can be an important sign. Once a toddler starts trying to climb over the cot rails, there is a greater chance of falling. If this is happening regularly, it may be time to consider a safer sleeping setup.
3. What can I do to make the move from a cot to a bed easier?
Give your child some time to get used to the idea. Let them spend time on the new bed during the day, choose between a couple of bedding options, and keep their usual bedtime routine. Familiar things can make a new sleeping space feel less unfamiliar.
4. What if my toddler keeps leaving their bed at night?
Try not to make each trip out of bed into a big event. Calmly take your child back, give them a simple reminder that it's bedtime, and repeat the same response when needed. With consistency, most children gradually learn that bedtime hasn't changed just because the cot is gone.
