When to Move Your Child to a Toddler Bed
Updated September 2025 · 5 min read
Most children move from a cot to a toddler bed between about 18 months and 3.5 years, with many around 2.5–3. The clearest sign it’s time is when your child starts climbing out of the cot, which becomes a safety risk. Other triggers include potty training or a new baby needing the cot. Make the move when your child is ready rather than by a fixed age, and baby-proof the room first.
- Most transition between about 18 months and 3.5 years (often 2.5–3).
- The biggest signal is climbing out of the cot — a safety risk.
- Baby-proof the whole room first: the bed is no longer a barrier.
- Keep the bedtime routine the same to ease the change.
There’s no fixed age
Children move to a toddler bed anywhere from about 18 months to 3.5 years, with many making the switch around 2.5 to 3. Readiness matters more than a birthday, so watch your child rather than the calendar.
Signs it’s time
- Climbing (or trying to climb) out of the cot — the biggest reason to switch, because falls from a cot can hurt.
- Potty training — a bed lets your child get to the potty at night.
- A new baby on the way who’ll need the cot (make this move a few weeks before the birth so it doesn’t feel like being “replaced”).
- Your child simply seems too big for the cot.
If your child is happy and safe in the cot, there’s no rush — many are fine in a cot until around three.
Baby-proof the room first
Once your child can get out of bed freely, the whole room needs to be safe:
- Anchor furniture to the wall and remove anything they could climb or pull over.
- Cover sockets and secure blind cords.
- Use a bed guard rail to prevent rolling out.
- Consider a stair gate on the bedroom door or across the top of the stairs.
Making the switch smooth
- Keep the bedtime routine identical — same steps, same timing — so only the bed changes.
- Involve your child — let them help choose bedding to build excitement.
- Expect some testing: if they get up, calmly and consistently return them to bed.
- Place the bed in the same spot the cot was, if you can, for familiarity.
