Toddler Climbing Out of the Cot

Treat the first climb as a safety problem

The risk from a climbing toddler is not that they get out. It is the fall on the way. A cot side is roughly chest height on a toddler standing on the mattress, and a child going over it head-first lands on a hard floor from well above their own height. That is why the response on the first night should be a physical change to the cot, not a behavioural plan.

What to change tonight

Lower the mattress base to its lowest setting if it is not already there. Most cots have two or three positions, and many families never move off the highest one after the newborn months. Dropping the base raises the effective height of the sides relative to your child and is the single most effective change available.

Then remove everything climbable from inside the cot: bumpers, large soft toys, pillows, sleep positioners and anything stacked against the sides. The Lullaby Trust does not recommend the use of any sort of cot bumper and urges parents to use a flat, firm mattress in a cot or Moses basket with no loose bedding, pillows or bumpers. It notes that bumpers pose a threat once babies begin to roll and move about the cot, because some infants have become entangled in the ties and material, or have fallen while pulling themselves up on the bumpers. For a climber, a bumper is a step.

Finally, move the cot away from anything outside it that could be grabbed or landed on: shelves, curtain cords, blind cords, radiators, chests of drawers and lamps. Clear the floor around the cot and consider a rug, though a rug is a mitigation and not a solution.

What safer sleep guidance says about the inside of the cot

The safer sleep advice does not change because your child is older and more mobile. The Lullaby Trust's position on sleeping position is that once your baby can move themselves from their back to their front and back again by themselves, they will be able to find their own sleeping position, and that the first few times they roll onto their tummy you might like to gently turn them back but do not have to get up all night to check. The same principle applies to a toddler who now moves freely: what you control is the environment, not the position.

The American Academy of Pediatrics and Red Nose Australia both describe the same environment for the whole first year and beyond into the cot years: a firm, flat sleep surface, no loose bedding, no pillows, no soft objects, nothing that raises or props the child.

Things sold to stop climbing

Cot tents, mesh cot toppers and crib nets are widely sold and are not endorsed by UK, Irish, US or Australian safer sleep guidance. None of these bodies lists them among recommended sleep equipment, and adding an unrecommended structure over a sleep space introduces entrapment and entanglement risks that the flat, firm, empty cot exists to avoid. Sleep sacks that restrict leg movement are sometimes suggested as a climbing deterrent; a well-fitting sleeping bag of the correct size is standard safer sleep equipment, but a bag chosen deliberately to restrict a child is not.

Deciding whether to move to a bed

There is no official age for moving from cot to bed, and no health body sets one. In practice, the move is usually driven by one of two things: the child can climb out, or the child has outgrown the cot. If your toddler climbs out repeatedly despite a lowered base and a cleared cot, the cot has stopped doing its job and a bed is generally safer than a cot they keep falling out of.

A single climb during an unsettled week, on the other hand, is not necessarily the end of the cot. Many children try it once, find it unrewarding and stop. Lower the base, wait a fortnight, and see whether it becomes a pattern.

If you do move to a bed

The room becomes the sleep space rather than the cot, so it needs the same scrutiny the cot got. Anchor chests of drawers, bookcases and wardrobes to the wall, because a toddler with floor access will climb furniture. Fit a stair gate at the bedroom door or the top of the stairs. Remove blind and curtain cords or fit safety cleats. Cover unused sockets. Check that windows have restrictors. Keep the bed low and consider a bed guard, and keep the floor beside the bed clear.

The bedtime behaviour that follows

Moving to a bed, or lowering the cot and holding the line, usually comes with a period of getting up. NHS guidance for under-5s is direct about this: set a limit on how much time you spend with your child when you put them to bed, for example read only one story then tuck them in and say goodnight; if your child gets up, keep taking them back to bed again with as little fuss as possible; try to be consistent, and expect to repeat the routine for several nights.

The AAP makes a similar point about toddler bedtime resistance: consistency matters more than the specific method, and a routine that varies from night to night makes the testing last longer.

When to get advice

Speak to your GP, health visitor or public health nurse if your child has fallen from the cot and hit their head, if climbing is accompanied by a marked change in sleep, mood or development, or if nothing you change reduces the risk and you are worried about injury. If your child has additional needs or a physical condition that makes falls more dangerous, ask for a referral for specific sleep and safety advice rather than adapting general guidance yourself.
