When should my toddler move from cot to bed?

Q: When should my toddler move from cot to bed?

Whenever they can climb out (safety forces the issue) or around age 2–3 otherwise — there’s no developmental deadline, and later is usually easier. Fit a bed guard, childproof the whole room as if it were the cot, and expect a novelty phase of midnight wandering that consistency settles within a couple of weeks.

The two triggers that force the move

Climbing out — once a toddler can get a leg over the rail, the cot has become a falling hazard and the move is immediate, whatever their age.
Outgrowing it — most cots are done by age 3 on size alone; cotbeds buy longer.

Absent either, there's no rush. Toddlers under about 2½ generally don't understand "stay in bed" as a concept, which is why moving early often trades a contained sleeper for a wandering one.

Setting the room up

Treat the whole room as the cot: anchor furniture to the wall, clear blind cords, gate the landing or the bedroom doorway, and assume everything reachable will be investigated at 2am.
A bed guard (or the cotbed's toddler rail) prevents rolling out during the settling-in weeks.
Keep everything else identical — same sleeping bag or bedding transition done separately, same routine, same bedtime.

The novelty phase

Expect a spell of jack-in-the-box bedtimes and midnight appearances. The boring, consistent response — calmly returning them with minimal chat, every time — settles it within a couple of weeks for most families. Big changes (new sibling, potty training) are worth spacing away from the move if you can.
