How To Stop A Toddler Climbing Out Of Cot

Back to Baby Sleep
That moment when you hear a thump, or walk in to find your little one proudly standing on the wrong side of their cot, is often followed by a wave of panic and the realisation that things have to change, and quickly! If you're feeling a bit overwhelmed about what's next, you're not alone. A toddler climbing out of the cot is one of the most common (and most challenging) phases of toddlerhood. It's a huge leap in their independence, which is exciting, but we also want to get you ready for it and keep all that lovely sleep you've worked so hard for intact.

Just need the quick answer? 

Lower the cot mattress to its lowest setting, remove anything your toddler could use as a step, and keep bedtime calm and predictable. Red Nose Australia says that once your toddler is trying to climb out of their cot and looks like they might succeed, it's time to move them to a new sleep space, usually between 2 and 3½ years, but sometimes as early as 18 months.

Why Toddlers Climb Out Of The Cot

Climbing is a normal developmental milestone, not bad behaviour. As toddlers get stronger and more coordinated, often somewhere between 18 months and 3 years, they work out how to climb, and getting over the side of the cot feels like a thrilling achievement.

Common reasons toddlers climb:

  • New physical skills: they can do it, so they want to practise. Again and again.
  • Curiosity: the cot side becomes a challenge, and they want to explore what's beyond it.
  • Seeking connection: climbing out in the middle of the night is often just the fastest route to you, and those cuddles you're so good at giving.

Safety Risks Of Cot Climbing

The most urgent risk is a fall. A tumble from the top of the cot side onto a hard floor can cause serious injuries, including head injuries and broken bones, so it's worth acting quickly once climbing starts.

Red Nose Australia says that when you see your child trying to climb out of the cot, and looking like they might succeed, it's time to move them to a new sleep space. For most children that happens somewhere between 2 and 3.5 years, but it can be as early as 18 months.


If you do see your child try to climb, keep your reaction calm. Telling them off rarely helps, because your toddler isn't being naughty, and a big reaction can encourage them to try it again.

Tips To Prevent Cot Climbing

Lower The Mattress
This is your first, best and easiest step. Lower the cot mattress to the lowest possible setting. Even a few extra centimetres can make a difference. The more distance there is between the cot mattress and the top of the cot side, the harder it is for your toddler to climb over. If your cot has multiple base heights, set it to the lowest one.
Using A Sleeping Bag
A well-fitting baby sleeping bag is often one of the simplest ways to make climbing out of the cot harder. A sleeping bag limits the leg movement a toddler needs to get leverage and swing a leg over the top of the cot side. The benefit: it keeps their feet enclosed, making it tricky to step up or balance on the side.

Dreamer Tip

Once your toddler is out of the cot and up on their feet, sleepwear with legs makes more sense, so they can walk around without tripping over a bag. That's where the Love to Dream™ Sleep Suit will be the shining star of your bedtime routine.

Remove Climbing Aids

Kids are so clever! Take a good look in and around the cot and remove anything that could become a step:

  • Large soft toys and pillows
  • Cot bumpers and extra blankets (Red Nose advises against cot bumpers in any case)
  • Furniture close to the cot, like a chest of drawers, feeding chair or shelf

Establishing A Consistent Bedtime Routine

The more settled and secure your toddler feels at lights out, the less motivated they are to escape later.

  • Predictability is security: try the same order every night, like bath, PJs, sleeping bag, a quiet story and cuddles.
  • Wind down properly: keep the last 15 to 20 minutes calm and low-light, with no screens or rough and tumble.
  • Keep it comfy: soft, breathable sleepwear in the right TOG for the room helps them settle and stay put.

Establishing A Safer Sleep Space

Now that your toddler is a potential explorer, it's worth treating their whole room as a childproofed space, all night long.

  • Anchor all furniture: this one is non-negotiable. Fix chests of drawers, bookshelves and any heavy furniture to the wall with anti-tip straps, as the ACCC recommends. If your toddler climbs the furniture, this stops it toppling over and causing serious injury.
  • Check blind cords and power points: keep blind and curtain cords secured well out of reach, and cover any power points little hands can get to.
  • Secure the door: if your little one is regularly escaping, a safety gate across the bedroom doorway can keep them safely in their room and away from the stairs and other hazards in the middle of the night.

When To Move From A Cot To A Toddler Bed

If you've tried all the prevention tips and your little one is still climbing out of the cot, it's time, for safety's sake, to make the move to a toddler bed.

While many sleep consultants suggest waiting until closer to age three, when impulse control is a bit better, safety always comes first. If the risk of a fall is high, the move needs to happen.

Making The Move Smoothly

  1. Involve them in the change: let your toddler help pick out their bedding or a cosy new companion for their new big kid bed. Make it feel like an exciting milestone.
  2. Start with a toddler bed: a toddler bed (or a mattress on the floor) sits lower to the ground than a single bed, so any tumbles are shorter. If you add a bed rail, choose one that fits tightly against the side of the mattress, with no gaps between bars bigger than 95 mm.
  3. Embrace "the walk back": your toddler will get out of bed. The key is to be consistent, calm and a little bit boring. Quietly walk them back to bed, tuck them in and leave. Repeat as many times as needed (it may feel like 100!) without showing frustration or excitement. It does get easier.

How Comfortable Sleepwear Can Help Get Better Sleep

A comfortable toddler is a more settled toddler. Being too hot, too cold or tangled in kicked-off blankets are all good reasons to wake up and go wandering.

Love to Dream™ sleepwear is designed for exactly this stage. In the cot, the Sleep Bag keeps them warm without loose blankets. Once your little one moves to a big kid bed, the Sleep Suit has legs, so they can stand, walk and move freely while staying cosy all night. Both come in a range of TOG ratings to suit the season.

It won't turn a climber into a sleeper overnight (we're working on that miracle!), but it does take discomfort off the list of reasons to get up.

FAQs About Toddlers Climbing Out Of The Cot

When do toddlers start climbing out of the cot?

Many toddlers start trying somewhere between 18 months and 3 years, as their strength and coordination develop. Every child is different, so some start earlier and some never try.

How do I stop my toddler climbing out of the cot?

Lower the mattress to its lowest setting, remove soft toys, bumpers and any nearby furniture they could climb on, and keep bedtime calm and consistent. A sleeping bag can make climbing harder, but if your toddler is still getting out, it's time for a toddler bed.

When should I move my toddler from a cot to a bed?

Red Nose Australia says once your toddler is trying to climb out of the cot and looks like they might succeed, it's time to move them to a new sleep space. For most children this is between 2 and 3.5 years, but it can be as early as 18 months.

Can a sleeping bag stop a toddler climbing out of the cot?

It can make it harder, but it won't stop a determined climber. Once your toddler is getting out, switch to a toddler bed and sleepwear with legs, like a Sleep Suit, so they can move around more easily.
