When to Move from a Cot to a Toddler Bed: Signs, Safety & Choosing the Right First Bed

There is no single perfect age to move a child from a cot to a toddler bed. For most families, the transition happens somewhere between 18 months and 3 years, but the right time depends more on your child’s development, behaviour and safety than their birthday.

If you're starting to look at toddler beds, you're probably wondering whether now is the right time to make the move.

Some toddlers are ready for a first bed quite early. Others feel secure in their cot for longer. The key is to look for signs that the cot is no longer the safest or most practical sleep space, while also making sure your child is ready for the extra freedom that comes with a bed.

In this guide, we’ll cover when to move from a cot to a toddler bed, the signs your child may be ready, how to make the change easier, and what to look for when choosing their first toddler bed.

Quick answer: when should you move from a cot to a toddler bed?

Many children move from a cot to a toddler bed between around 18 months and 3 years old. This is a broad range because children develop at different speeds. The main reason to move sooner is safety — for example, if your toddler is regularly trying to climb out of the cot.

If your child is happy in their cot, not trying to climb out and still has enough space, there is usually no need to rush. Moving too early can sometimes lead to bedtime battles, wandering around the room or more night waking simply because your child suddenly has more freedom.

Signs your child may be ready for a toddler bed

Your child may be ready to move from a cot to a bed if you notice several of these signs:

• They are trying to climb out of the cot, even when the mattress is on the lowest setting.
• They have outgrown the cot or seem uncomfortable with the space available.
• They can get in and out safely and are steady on their feet.
• They understand simple bedtime boundaries, such as staying in bed or waiting for you in the morning.
• They can communicate basic needs, such as needing a drink, the toilet or comfort.
• They are showing interest in a “big bed” or asking for one.
• You need the cot for a new baby, although it is best not to make the change feel sudden or forced.

One sign on its own does not always mean you need to move immediately. A toddler asking for a big bed, for example, is not the same as being ready to sleep safely and calmly in one. But if your child is climbing out, too tall for the cot or clearly unsettled by the lack of space, it may be time to start planning the transition.

Signs it may be too soon

It may be better to wait a little longer if your toddler:

• is still sleeping happily and safely in the cot
• is not trying to climb out
• struggles to follow simple bedtime instructions
• regularly gets out of bed or leaves the room during the night
• is going through another big change, such as moving house, starting nursery or welcoming a new sibling

If a new baby is on the way and you need the cot, try to make the transition well before the baby arrives. This helps your toddler feel that their new bed is a positive step, rather than something taken away from them.

Should you move straight to a single bed?

This is one of the biggest questions parents ask when they start researching toddler beds. Should you buy a toddler bed, use a cot bed, choose a floor bed, or move straight to a single bed?

The answer depends on your child’s age, size, confidence and how much space you have at home.

Cot bed

If you already have a cot bed that converts into a toddler-style bed, this can be the easiest first step. The mattress size usually stays the same, the sleep space feels familiar, and the change can feel less dramatic for your child.

The downside is that not every cot bed feels like a proper first bed, and some children may outgrow it fairly quickly depending on the size.

Toddler bed

A toddler bed is smaller than a single bed and often lower to the floor. Many use a 70 × 140 cm mattress, which is the same size as many cot bed mattresses. This can make the transition smoother and less overwhelming than moving straight into a full-size single bed.

Toddler beds can be a good option if your child is still little, you want a lower sleep space, or you are working with a smaller room.

Floor bed

A floor bed sits very low to the ground and is often used in Montessori-inspired bedrooms. The low height allows children to get in and out more independently, which can help them feel confident in their new sleep space.

Soft foam floor beds, such as our soft foam Montessori toddler beds, offer a softer version of this idea, with padded sides and no hard wooden corners.

Single bed

Some families choose to move straight to a single bed, especially if the child is older, taller or likely to outgrow a toddler bed quickly. A single bed can last longer and may work well for older toddlers or preschoolers.

However, a single bed can feel quite big for a child moving from a cot. It is also usually higher off the ground and may need a guard rail, especially in the early weeks.

How to make the cot-to-bed transition easier

The move to a toddler bed is a big step. A little preparation can make the change feel calmer and more exciting.

1. Keep the bedtime routine the same

Try to keep the rest of bedtime familiar. Bath, pyjamas, story, cuddle and lights out can stay exactly the same. The bed may be new, but the routine should feel predictable.

2. Talk about the new bed before it arrives

Introduce the idea gradually. Talk about a “new big bed” in a positive way, let your child look at pictures, and explain that it will be a special place for sleep, stories and rest.

3. Let your child help with small choices

They do not need to choose the whole bed, but small choices can help them feel involved. For example, they could choose a fitted sheet, a cushion for story time or where their favourite soft toy sits during the day.

4. Childproof the bedroom

Once your child can get out of bed, the whole room becomes part of the sleep space. Secure furniture to the wall, cover sockets, remove loose cords, keep small objects out of reach and make sure windows are safe. If your child may leave the room at night, think about stair gates and hallway safety too.

5. Expect a few unsettled nights

It is very normal for toddlers to test the new freedom. Calmly return them to bed, keep your response boring and consistent, and avoid turning bedtime into a long negotiation.

What should you look for in a first toddler bed?

The best toddler bed is one that suits your child’s stage, your room and the way your family uses the space. Before buying, think about:

• Height: A low bed is easier for toddlers to climb in and out of independently.
• Edges and corners: Rounded or padded edges can be reassuring for younger toddlers.
• Mattress size: Some toddler beds use a cot bed mattress size, often 70 × 140 cm, which can make the transition easier.
• Stability: The bed should feel secure and suitable for everyday use.
• Cleaning: Removable, washable covers or wipeable finishes are helpful during toddler years.
• Room layout: Think about where the bed will sit, whether one side will be against a wall, and whether there is space around it.
• How it will be used: Some first beds are only for sleep, while others double as a reading spot, quiet corner or play space.

You may also want to think about the wider room setup, including storage, soft furnishings and nursery furniture that can grow with your child.

Wooden toddler bed or soft foam toddler bed?

Traditional wooden toddler beds and soft foam floor beds can both work well. The right choice depends on your child and the type of room you want to create.

Wooden toddler beds

A wooden toddler bed feels more like a traditional bed. It may have a slatted base, a raised frame and sometimes a small guard rail. Wooden beds can be long-lasting and suit families who want a more classic furniture style.

The main thing to consider is that wood is hard. Corners, edges and raised sides can be bumped during play or when a child climbs in and out. Some children may also need a separate guard rail, depending on the design.

Soft foam toddler beds

A soft foam toddler bed is different. Instead of a hard wooden frame, the bed is made from soft foam with padded sides. It usually sits low to the floor, which makes it easier for toddlers to climb in and out independently.

This can be especially helpful for families looking for a Montessori-style floor bed or a softer first bed. The padded sides create a more enclosed feel, while the low height helps reduce the worry of a bigger fall from a raised frame.

Soft foam beds are also more than just a place to sleep. During the day, they can become a story corner, quiet space or little sofa-style area for your child’s room.

Is a soft foam bed safe for toddlers?

A soft foam bed can be a practical option for toddlers who are ready to move out of a cot, especially because it is low to the floor and has no hard wooden corners. However, it should still be used in an age-appropriate way.

The key benefits for toddlers are:

• Low height: The bed sits close to the floor, so getting in and out is easier and less daunting.
• No hard wooden corners: The soft foam construction helps reduce bumps from sharp or solid edges.
• Padded sides: Raised padded sides create a more enclosed sleep space without feeling like a traditional cot.
• Independence: Toddlers can climb in and out more easily, which suits Montessori-style rooms and children ready for more freedom.
• Multi-use design: The bed can also be used for stories, quiet time and resting during the day.

It is important to remember that a toddler bed is not a baby cot. For babies under 12 months, safer sleep guidance still focuses on a clear, firm, flat sleep space, such as a cot or Moses basket, with no loose bedding, toys or padded accessories in the sleep area.

For toddlers who are developmentally ready for a bed, a soft foam floor bed can offer a gentler alternative to a standard hard frame. As with any toddler bed, the room should be properly childproofed and the sleep setup should suit your child’s age and development.

Do you need bed bumpers or extra cushions?

For babies, padded bumpers and loose soft items should not be used in the cot. Safer sleep guidance for babies is very different from setting up a toddler or older child’s bed.

For older toddlers and children, families sometimes use soft bed cushions or braided bed cushions to make a bed feel more enclosed, especially when the child has moved into a toddler bed or single bed. These are not baby cot products and should only be used when the sleep setup is suitable for the child’s age and development.

You can view our braided bed cushions if you are looking for a softer edge for a toddler bed, floor bed or larger child’s bed.

What mattress should you use?

Always use a mattress that fits the bed correctly, with no large gaps around the edges. A firm, supportive mattress is important, and the mattress should be the recommended size for the bed.

For the Monio soft foam beds, the sleeping area is designed for a 70 × 140 cm mattress. The original mattress option is 10 cm thick, and the bed is suitable for mattresses up to 14 cm deep. This means the padded sides still sit above the mattress and create a raised edge around the sleeping area.

How to help your toddler stay in bed

Even when a toddler is ready for a bed, they may still pop out repeatedly at bedtime. That does not mean the bed is wrong. It usually means the new freedom is exciting.

Try these simple steps:

• keep the bedtime routine short and predictable
• explain the rule clearly: “It is sleep time. We stay in bed.”
• return them calmly each time without lots of conversation
• use a night light if they are nervous
• praise them in the morning for staying in bed
• avoid introducing the new bed during other stressful changes if possible

You may also find it helpful to build a calming bedtime space with soft lighting, familiar bedding and a consistent story-time routine.

So, when is the right time?

The right time to move from cot to toddler bed is usually when your child is no longer safely contained in the cot, has outgrown it, or is developmentally ready for more independence.

For many families, this happens between 18 months and 3 years. But if your child is safe, settled and happy in their cot, it is also fine to wait. The best transition is one that feels calm, planned and suited to your child.

Choosing the right first toddler bed

If you have decided your child is ready, the next step is choosing a first bed that feels safe, comfortable and practical for your home.

Our Monio soft foam toddler beds are designed to make the transition from cot to first bed as comfortable as possible. They feature a soft foam construction, raised padded sides, removable washable covers and a low floor-bed design to support independence.

Available in bouclé and corduroy finishes, they are a gentle alternative to traditional wooden toddler beds and can be used for sleep, stories, rest and quiet play.

Frequently asked questions

What age should a toddler move from a cot to a bed?

Many toddlers move between 18 months and 3 years, but readiness matters more than age. Climbing out, outgrowing the cot or showing the ability to follow simple bedtime boundaries can all be signs.

Can a 2-year-old sleep in a toddler bed?

Yes, many 2-year-olds can sleep in a toddler bed if they are developmentally ready and the room is safely set up. Look at whether your child can get in and out safely, understand simple bedtime boundaries and cope with the extra freedom of a bed.

Is it better to wait until age 3?

For some children, yes. If your toddler is safe and happy in the cot, waiting can make the transition smoother because older toddlers often have better impulse control.

Should I move my toddler straight to a single bed?

You can move straight to a single bed if your child is older, taller or likely to outgrow a toddler bed quickly. However, a single bed may feel large and high for a younger toddler, so some families prefer a toddler bed or low floor bed first.

What is the safest first bed for a toddler?

The safest option depends on your child and room setup. Look for a bed that is stable, low enough for safe access, uses the correct mattress size and suits your child’s development. The bedroom should also be fully childproofed.

Are floor beds good for toddlers?

Floor beds can work well for toddlers who are ready for more independence. They are low to the ground and easy for children to access, but the whole room needs to be made safe because the child can get out freely.

What is the difference between a wooden toddler bed and a soft foam toddler bed?

A wooden toddler bed has a hard frame and often feels more like traditional furniture. A soft foam toddler bed is lower, padded and has no hard wooden corners, making it a gentler option for toddlers who are moving into their first bed.

Do I need a toddler bed if I already have a cot bed?

Not always. If your cot bed converts safely into a toddler-style bed and your child is comfortable in it, that may be enough for the first stage. Some families still choose a separate toddler bed or floor bed if they want a lower, softer or more independent sleep space.
