Moving from a cot to a toddler bed is an important milestone for young children and their families. It often marks the moment when a child begins to gain a little more independence, while parents start navigating a new stage in their child’s sleep journey.
For some families, the change happens smoothly. For others, it can bring a few unsettled nights or a curious toddler who suddenly realises they can leave their bed whenever they like. Both experiences are completely normal.
There is no single “right age” to make the switch. Many children transition between 18 months and 3 years, but readiness often depends more on development and behaviour than age alone.
Understanding the signs that your child may be ready and preparing thoughtfully can make the process far calmer for everyone involved. Below, we look at the key signals to watch for, practical ways to prepare for the transition, and how families can support healthy sleep during this stage.
A toddler bed is a small bed designed for young children who have outgrown their cot but are not yet ready for a full-sized bed.
The main difference between a toddler bed and a cot is freedom of movement. A cot surrounds the child with high sides that keep them safely inside, whereas a toddler bed has lower sides or guardrails. These guardrails help prevent falls while still allowing children to climb in and out independently.
For many children, this new independence feels exciting. Being able to climb into bed on their own can give them a sense of control and confidence at bedtime.
At the same time, that freedom can also mean children experiment with getting up after lights out or exploring their room when they wake early. Because of this, routines and sleep expectations become especially important once the transition happens.
This stage of development often coincides with other milestones in early childhood, such as growing independence during daily rhythms and developing stronger sleep habits.
Every child develops at their own pace, but there are several common signs that it may be time to consider moving from a cot to a toddler bed.
One of the clearest signs is when a child starts climbing out of their cot. Once toddlers begin experimenting with climbing, the cot may no longer be the safest place to sleep.
Trying to climb over the sides can lead to falls or injuries, particularly at night when parents or carers are not nearby. If your child is consistently attempting to climb out, moving to a toddler bed may actually be the safer option.
Sometimes the signs are simply physical. If your child looks cramped in their cot, has their legs hanging over the edge, or seems uncomfortable while sleeping, they may have outgrown it.
Children who do not have enough space to stretch comfortably often sleep less peacefully and may wake more frequently during the night.
Curiosity about where and how people sleep can also signal readiness.
Some toddlers start asking to sleep in their parents’ bed or a sibling’s bed. Others may try climbing onto larger beds during playtime or show excitement when they see a bigger bed in their room.
This interest often reflects a growing awareness that sleeping arrangements can change as they grow.
Developmental changes can also influence sleep patterns. Toddlers who are learning to self-soothe or settle themselves back to sleep may be ready for the added independence a toddler bed provides.
Similarly, some children begin to resist naps in their cots or to ask for more autonomy during bedtime routines. While these behaviours can sometimes feel challenging, they can also signal that your child is moving into a new developmental stage.
Although recognising readiness signs is helpful, timing still matters. In some situations, it may be better to wait a little before making the change.
For many children, a stable sleep environment helps them feel safe and secure. If other changes are happening at the same time, postponing the transition can make bedtime easier for everyone.
Big events in a young child’s life can feel overwhelming. Starting nursery, moving home, welcoming a new sibling, or adjusting to a different routine can all create emotional shifts.
During periods like these, keeping sleep arrangements familiar can offer a sense of comfort and predictability.
Families connected with a UK nursery often notice that children benefit from consistent routines between home and early years settings, especially when several developmental changes happen at once.
If your child has recently been unwell, is waking frequently at night, or is struggling with disrupted sleep, introducing a toddler bed may add another layer of difficulty.
Waiting until sleep has returned to a more settled pattern can make the transition smoother.
Children sometimes become clingy or anxious at bedtime, particularly during developmental leaps.
If your child seems unsettled or reluctant to separate at night, it may help to delay the change until they feel more secure again.
Young children thrive on predictable routines. If your child is still adapting to a new nap schedule or bedtime rhythm, giving them extra time in their cot can help maintain consistency.
You can read more about the role routines play in children’s wellbeing in this guide on why children need routines and how to make them work for your family.
Some children develop a strong emotional connection to their cot because it represents comfort and familiarity.
If your child clearly feels safe and relaxed in their cot, there is no need to rush the transition unless safety becomes a concern.
Transitioning to a toddler bed can have a noticeable impact on sleep, at least in the short term.
Because children can now climb out of bed independently, they may test this new freedom. It is quite common for toddlers to get out of bed repeatedly during the first few nights or to explore their room when they wake early.
Although this can feel frustrating for families, it is usually a temporary stage.
Over time, many children develop stronger self-soothing skills as they adjust to their new sleeping arrangement. Being able to move independently can help them feel more confident about settling themselves when they wake at night.
Families looking for additional ideas to encourage healthy sleep habits may find useful guidance in supporting sleep. With patience and consistency, most families find that sleep settles again once the new routine becomes familiar.
Preparing a safe and comfortable sleep space can make a big difference when introducing a toddler bed.
A well-organised environment helps children feel confident in their new sleeping arrangement and gives parents peace of mind.
Start by making sure the toddler bed is sturdy and fitted with guardrails, and that the mattress fits snugly inside the frame.
It is also important to review the room itself. Secure furniture to the wall, remove loose cords, and keep small objects or choking hazards out of reach. Since toddlers can now leave their beds on their own, the entire room becomes part of their sleep space.
Bedtime routines provide reassurance and predictability. Continuing the same rituals your child already knows, such as reading a story or singing a lullaby, helps signal that it is time to wind down.
These familiar moments often make the transition feel far less intimidating.
Soft lighting, comfortable bedding, and favourite comfort toys can help make the new bed feel inviting. Some families also find that white noise or gentle background sounds support relaxation at bedtime.
Introducing the toddler bed during daytime naps can be a gentle way to help your child adjust. Once they become comfortable sleeping there during the day, transitioning to nighttime sleep often feels less daunting.
Allow your child to practise climbing into and out of the bed while you supervise. This builds confidence and helps reduce the chance of accidents during the night.
Sleep disruptions are common during the first days or weeks after moving to a toddler bed. One of the most frequent challenges is toddlers repeatedly getting out of bed after bedtime.
While this behaviour can test a parent’s patience, it is usually part of the adjustment process as children explore their new freedom.
If your child leaves their bed, calmly guide them back each time without turning the situation into a conversation or game.
Using a simple and consistent phrase such as “It’s bedtime now” can reinforce expectations without adding stimulation.
Keeping the room dimly lit and avoiding snacks, toys, or extra playtime helps children understand that nighttime is for sleeping.
With consistency, most toddlers gradually learn that getting out of bed will not lead to extra attention or activity.
Giving children small choices can make bedtime feel more collaborative. For example, they might choose which story to read, which blanket to use, or which soft toy to sleep beside them.
These small decisions allow children to feel involved while still maintaining a clear and predictable bedtime routine. Parents can also encourage small responsibilities, such as fetching their comfort toy or helping switch off the bedside light.
Celebrating positive behaviour can be helpful too. Some families use sticker charts or simple praise when their child stays in bed through the night. Over time, these small steps help children develop confidence and a stronger sense of independence at bedtime.
Seasonal clock changes can also influence children’s sleep patterns, especially when the clocks go forward in the Spring.
When daylight shifts, children may wake earlier in the morning or feel tired at different times in the evening. A child who usually sleeps from 7 p.m. to 6 a.m. might suddenly feel ready to wake closer to 5 a.m.
Because young children are particularly sensitive to changes in routine and daylight, it can take several days for their body clocks to adjust.
Families who are transitioning to a toddler bed around the same time may notice a few extra disruptions while sleep patterns settle.
More guidance on this seasonal shift can be found in Sleep: surviving the clock change.
Preparing gradually can make the Spring clock change easier.
In the days leading up to the change, try moving naps, meals, and bedtime earlier by around fifteen minutes every few days. This gradual adjustment helps the body adapt more comfortably.
Natural daylight also plays an important role in regulating sleep cycles. Spending time outdoors during the day helps reinforce healthy rhythms, while blackout blinds can prevent early-morning light from waking children too early.
Even with preparation, some temporary disruption is still normal. Most children settle into the new routine within a few days.
The move from a cot to a toddler bed is a significant step in a child’s development. While it can bring a few challenges at first, it also offers children opportunities to build independence and confidence.
By watching for signs of readiness, maintaining familiar routines, and responding with patience, families can help make the transition feel calm and reassuring.
Every child moves at their own pace, and there is no need to rush the process. With gentle guidance and plenty of reassurance, most children quickly grow comfortable in their new sleeping space.
Early years educators and families often work together during this stage, sharing observations about sleep routines and encouraging children to develop independence in ways that feel supportive and positive.
With time, consistency, and encouragement, the transition to a toddler bed becomes just another step in a child’s journey of growth.
