Most toddlers make the cot to bed move somewhere between about 18 months and 3 years, and the clearest sign it is time is when your child starts climbing out of the cot. If your toddler sleeps well and stays put, there is no rush: many children are happier and safer in a cot until closer to 3. When you do switch, keep the new bed low, make the whole bedroom safe for a child who can now get up at night, and keep your bedtime routine exactly the same.
This guide covers the signs your toddler is ready, how to choose between a toddler bed, floor bed or single bed, how to make the move step by step, room safety in an HDB flat and what to do when your child keeps getting out of bed.
When to move from a cot to a bed
There is no set age. Instead, watch for these signs:
- Climbing out, or trying to. This is the main safety reason to move. A fall from the top of a cot rail is higher than a roll from a low bed. The American Academy of Pediatrics’ parenting site, HealthyChildren.org, says that once your toddler can climb out of the cot, it may be time to switch.
- Outgrowing the cot. If the top rail is below chest height with the mattress on its lowest setting, your child can probably tip over it.
- Night-time potty training. A child who is learning to stay dry at night needs to be able to get to the toilet or call you.
- A new baby needs the cot. This is common, but time it carefully (see below).
These are not reliable signs on their own: early waking, protesting at bedtime or a sleep regression. Moving to a bed rarely fixes these, and the extra freedom can make bedtime harder for a while.
If a new sibling is on the way
Try to make the move at least a couple of months before the baby arrives, or wait until a few months after, so your toddler does not feel pushed out of “their” bed by the newcomer. Talking it up as a “big kid” bed helps. Our guide to preparing a toddler for a new baby has more ideas.
Toddler bed, floor bed or single bed?
| Option | Pros | Cons |
|---|---|---|
| Convertible cot (side removed) | Familiar bed and mattress; no new purchase | Only possible if your cot is designed to convert |
| Toddler bed with rails | Low to the ground; uses a cot-sized mattress; fits small HDB rooms | Outgrown by around school age |
| Floor bed or mattress on the floor | No fall risk; child can get in and out independently; Montessori-friendly | Needs a fully child-proofed room; mattress needs airflow in humid weather |
| Single bed with guard rail | Lasts for years; one purchase | Higher fall height; guard rails must fit properly |
For specific models sold in Singapore, from budget IKEA frames to Montessori floor beds, see our round-up of the best toddler beds in Singapore.
In Singapore’s humidity, a mattress lying directly on the floor can trap moisture underneath. Choose a floor bed frame with slats, or lift and air the mattress regularly to prevent mould.
How to make the switch, step by step
- Pick a calm time. Avoid weeks with other big changes, such as starting childcare, moving house, illness or travel.
- Involve your toddler. Let them help choose the sheets or a soft toy for the new bed. Read a picture book about big-kid beds.
- Put the bed where the cot was, if space allows, so the room still feels familiar.
- Start with naps or go straight to nights. Some children do well practising with naps first. Others cope better with a clean switch. Either works if you are consistent.
- Keep the routine identical. Same bath, book, song and lights-out time. Our toddler sleep schedule has sample routines by age.
- Explain the one rule. Once it is sleep time, we stay in bed until morning, unless we need the toilet.
- Praise in the morning. Notice and celebrate staying in bed, even if it was only part of the night.
Expect some ups and downs for one to three weeks. Many toddlers are good for the first few nights, then test the new freedom once the novelty wears off.
Bedroom safety once your toddler can get up
When your child moves out of a cot, the whole bedroom effectively becomes their cot. Go through the room at toddler height:
- Windows: keep the bed and any climbable furniture away from windows. In HDB flats, fit window grilles or restrictors and keep them locked. Our guide to window safety and HDB grilles explains what to look for.
- Blind and curtain cords: tie them up out of reach or use cordless blinds, as looped cords are a strangulation risk.
- Furniture: anchor wardrobes, chests of drawers and bookshelves to the wall to prevent tip-overs. Do not put a TV on a dresser in the child’s room.
- Bed gaps: make sure the mattress fits the frame snugly, and that there is no gap between the guard rail, the mattress and the wall where your child could get trapped.
- Electrical points and cables: cover sockets and secure cables from fans, lamps and night lights.
- Small objects and medicines: remove coins, button batteries, cosmetics and anything that could be swallowed.
- The door: consider a safety gate across the bedroom doorway so your toddler cannot wander the flat while you sleep.
- Bunk beds: children under 6 should not sleep on the top bunk.
Handling night wandering and bedtime battles
Getting out of bed again and again is the most common problem after the switch. A calm, boring and consistent response works best:
- Return them quietly. Walk your child back to bed with few words and little eye contact. Repeat as often as needed. The first nights can take many returns.
- Don’t make it fun. Avoid letting them join you on the sofa, watch a screen or come into your bed, which rewards getting up.
- Try a toddler clock. A sleep clock that changes colour when it is time to get up gives a clear visual cue, especially for early risers.
- Use a simple reward chart for children around 3 and older: a sticker for staying in bed, with a small treat after a few stickers.
- Meet the real needs first. A last drink, a toilet trip and a comfort object before lights out reduce “one more thing” requests.
- Night fears are real. A dim night light and a reassuring check-in can help. Screaming episodes in the first hours of sleep where your child seems awake but can’t be comforted may be night terrors, which are handled differently.
If the transition is not working after a few weeks and your child is under 3 and safe in the cot, it is fine to go back to the cot and try again in a few months. That is not a failure.
When to talk to a doctor
See your paediatrician or polyclinic if your child snores loudly most nights, pauses in breathing during sleep, is very sleepy during the day, or has sleep problems that are affecting the whole family despite a consistent routine.
The bottom line
Move from cot to bed when your toddler starts climbing out or outgrows the cot, usually between 18 months and 3 years. Choose a low bed, child-proof the whole room, especially windows, cords and furniture, and keep the bedtime routine the same. Expect a few weeks of testing, and respond to night wandering calmly and consistently.
What is the best age to move from a cot to a bed?
Most children move between about 18 months and 3 years. Safety is the main guide: switch when your child can climb out or the rail is below chest height, rather than at a set age.
Should I use a toddler bed or go straight to a single bed?
Either is fine. A toddler bed is lower and uses a cot-sized mattress, which suits small rooms. A single bed with a properly fitted guard rail lasts longer but has a higher fall height.
What do I do if my toddler keeps getting out of bed?
Return them to bed calmly and quietly every time, avoid rewarding night-time visits, and praise them in the morning. A toddler sleep clock and a sticker chart can help older toddlers.
Is a floor bed safe for a toddler?
A floor bed removes the fall risk, but your toddler can get up freely, so the whole room must be child-proofed. In Singapore’s humidity, use a slatted base or air the mattress regularly to prevent mould.
