Cot to Toddler Bed Transition | When to Move & How to Do It

When to make the move

The best time is when your toddler is developmentally able to follow the 'stay in bed' rule — usually 2.5–3.5 years. Moving earlier than this often leads to repeated getting-out because the impulse control just isn't there yet.

Move earlier only if your toddler is climbing out of the cot and there's a real safety risk. A new sibling arriving is not, on its own, a reason to move before your toddler is ready — a second cot or bassinet buys time.

Safety-proofing the room

Once your child is in a bed, they can get up and roam. The room needs to be safe enough for them to be in it, awake, unattended.

• Anchor all furniture to the wall (dressers, shelves, TVs).
• Cordless blinds only.
• Cover power points.
• Consider a stair gate at the bedroom door for the first few weeks.
• Remove anything they could climb on to reach a window.

Choosing the right bed

Options range from a cot bed (side removed) to a floor bed, low toddler bed or a full single with a rail. The safest option is the one closest to the ground with sides that stop rolling out.

• Cot bed converted: low cost, familiar smell, easy transition.
• Floor mattress: safest for climbers, cheapest, easy.
• Toddler bed: low, small, but not needed if you already have a single.

How to introduce the new bed

Involve your toddler in the change so it feels like a promotion, not a loss.

• Let them pick the sheets or a small special pillow.
• Practise 'staying in bed' at bedtime for a few nights while the cot is still up.
• Keep the exact same bedtime routine — same order, same time, same songs.
• Talk positively about the change during the day, not at 6.55pm.

What to do when they keep getting out

Almost every toddler tests the new freedom. Consistency in the first two weeks sets the pattern for the next year.

• Return them calmly, with as few words as possible.
• Same short phrase every time: 'It's sleep time. Back to bed.'
• Avoid getting drawn into conversation, negotiation or story.
• Return as many times as needed — 20 times on night one is normal.

Middle-of-the-night wandering

It's common for toddlers to appear at your bed at 2am in the first few weeks. Decide the plan before bedtime so you're not making a policy at 2am.

A floor mattress in your room, or walking them straight back with minimal fuss, both work — as long as you do the same thing every night.

Common questions

What age should I move my toddler to a bed?

Most Australian sleep experts recommend 2.5–3.5 years. Moving earlier often causes repeated getting-out because the impulse control isn't yet there.

Should I move my toddler to a bed before the new baby arrives?

Only if they'd be ready anyway. If they're under 2.5 and settled in the cot, borrow a second cot or bassinet rather than force an early transition.

My toddler climbs out of the cot — do I have to move them?

If the climbing is a real safety risk, yes. Try lowering the mattress and removing sleep-bag climbing aids first. If they're still climbing out, move to a low or floor bed.

What kind of bed is safest for a toddler?

A floor mattress or low toddler bed is the safest starting point. If you're using a single bed, add a rail to prevent rolling out.

Should I use a stair gate at the bedroom door?

For the first few weeks, yes — it keeps the child safely in the room without you needing to lock them in. Some families keep it long-term for peace of mind.

What do I do when my toddler keeps getting out of bed?

Return them calmly with a short repeated phrase — 'It's sleep time. Back to bed.' — as many times as needed. Consistency for the first two weeks sets the pattern.

My toddler keeps coming into my bed at night — is that OK?

It's fine if it's the family plan. If you'd rather they stay in their own bed, walk them straight back with minimal fuss or set up a floor mattress in your room as a middle option.

How long does the transition take?

Most families settle into the new bed within 2–3 weeks with consistent responses. The first week is usually the hardest.
