You hear a thump.

Then little feet in the hallway.

Your toddler has escaped the crib.

It may look clever.

It is also a safety signal.

Once a child can climb over the crib rail, the crib is no longer doing its main job.

It is no longer keeping the child safely inside.

The next goal is not to find a trick that makes climbing harder.

The goal is to make sleep safe again.

For the full toddler sleep and development picture, start with the Complete Toddler Guide for Ages 1 to 3.

1. Stop Treating the Crib Escape as a Sleep Game

A toddler who climbs out once has shown you something useful.

They can do it.

Do not wait for escape number five.

Current CPSC crib warning language says:

Stop using the crib when the child begins to climb out or reaches 35 inches, which is 89 cm.

This matters because climbing over the rail creates a fall risk.

Parents sometimes search crib escape toddler hoping to find a trick that keeps the child inside.

The better question is:

What sleep space is safe now that my toddler has learned this skill?

That shift makes the next decision much easier.

2. Check the 35 Inch Crib Limit

Height matters too.

HealthyChildren advises moving a child to another bed when the child reaches about 35 inches, or 89 cm.

It also warns about a crib rail that has become low compared with the child's body.

You do not have to wait for a fall.

You also do not have to wait until age 3.

A shorter toddler who climbs can outgrow the crib before reaching the height limit.

A taller child can reach the height limit before ever trying to climb.

Think of the rule as:

• Climbing out means stop
• 35 inches means stop
• Your crib maker may set another limit that also matters

Always read your own crib manual.

3. Lower the Mattress Before Climbing Starts

This step helps before the child becomes an escape artist.

HealthyChildren recommends putting the crib mattress at its lowest approved position before a child learns to stand.

A lower mattress makes the crib rail harder to get over.

But timing matters.

If your toddler has already begun climbing out, lowering the mattress is not a reason to keep using the crib past the stop point.

Use the lowest setting early.

Do not use it as a way to ignore a successful escape.

4. Remove Anything Your Toddler Can Use as a Step

Toddlers see climbing tools everywhere.

A large stuffed toy becomes a step.

A thick bumper becomes a foothold.

A pile of toys becomes a platform.

HealthyChildren tells parents to remove large toys and other objects that can help a child climb.

Keep the crib simple.

Do not add items to make the sides feel softer or taller.

This is useful during early crib climbing, before the child has actually escaped.

Once the child is getting over the rail, move to the next sleep setup.

5. Make the Whole Bedroom Safe

This is the biggest change.

In a crib, the crib was the main safe zone.

After the move, the bedroom becomes the safe zone.

Your toddler may wake while you are asleep.

They may explore.

They may climb furniture.

They may open drawers.

They may reach a window.

Nationwide Children's recommends childproofing the whole room once a toddler can get out of bed alone.

Check these areas before the first night:

This is the heart of sleep safety toddler planning.

The child has more freedom now.

The room has to match that freedom.

6. Choose the Next Bed Carefully

You have a few options.

A toddler bed

CPSC defines a toddler bed as a bed made for a full size crib mattress and intended for a child who is at least 15 months old and weighs no more than 50 pounds.

Use a product that meets current safety rules.

Follow the maker's age, size, mattress, and assembly instructions.

A convertible crib

Some cribs turn into toddler beds.

This can make the move simple.

Use only the correct parts.

Follow the crib maker's instructions.

Do not make your own conversion.

A low larger bed

Some families move straight to a low twin bed.

If you choose this route, look closely at:

• Bed height
• Mattress fit
• Possible gaps
• Bed rail safety
• Distance from walls and windows

A low sleeping surface reduces the distance of a possible fall.

For a full guide to the crib to bed transition, read the Toddler Bed Transition Guide.

7. Skip Crib Tents and Homemade Barriers

Do not turn the crib into a cage.

Do not add homemade netting.

Do not build a taller rail.

Do not change the crib frame unless the manufacturer designed that change.

Do not depend on a crib tent to stop an escape.

CPSC has previously recalled crib and play yard tents because of entrapment and strangulation hazards.

The safest lesson is simple.

Do not fix one hazard by creating another one.

If your toddler has outgrown the crib's safe use, change the sleep space.

8. Use Bed Rails With Care

Bed rails deserve more thought than many parents give them.

CPSC says portable bed rails are intended for children who can get into and out of an adult bed without help.

This is usually around ages 2 to 5.

They are not intended for children under age 2.

A poorly fitted rail can leave a dangerous gap between the rail and mattress.

That gap can trap a child.

CPSC issued new warnings in 2026 about some portable rails that failed entrapment safety requirements.

If you use one:

1. Check the child's age
2. Check the bed type
3. Use the correct mattress
4. Follow every installation step
5. Check for gaps
6. Check current recalls or safety warnings

Do not assume every product called a toddler rail is safe for every toddler.

9. Keep the Bedtime Routine the Same

Change the sleep surface.

Do not change everything else.

Keep the same bath.

Keep the same pajamas.

Keep the same book.

Keep the same song.

Keep the same bedtime phrase.

HealthyChildren recommends keeping the familiar bedtime routine after a move from crib to bed.

That helps the new setup feel less strange.

For a simple plan, use the Toddler Bedtime Routine Guide.

10. Return Your Toddler to Bed Calmly

The new bed gives your toddler a superpower.

They can leave.

Expect them to test it.

You may hear:

“Water.”

“One more hug.”

“I need my bear.”

“I am not tired.”

Do not make each exit interesting.

Walk your child back.

Use very few words.

You can say:

“It is bedtime.”

Then leave again.

If they come out again, repeat the same response.

HealthyChildren recommends calm, quiet returns to bed and keeping the routine predictable.

This is boring.

Boring is useful.

11. Check the Rest of the House at Night

The bedroom may not be the only place your toddler can reach.

Can they open the bedroom door?

Can they reach stairs?

Can they reach an outside door?

Can they reach a bathroom?

Can they get into medicine, cleaning products, batteries, or sharp items?

Nationwide Children's recommends thinking beyond the bedroom once a child can leave bed alone.

Use appropriate stair gates where needed.

Secure dangerous products.

Make sure adults can reach the child quickly in an emergency.

A toddler who was safely contained yesterday can explore much farther tonight.

Is My Toddler Ready for a Bed?

This question needs two answers.

There is toddler bed readiness.

Then there is crib safety.

Your child may not feel emotionally ready.

They may love the crib.

They may get out of the new bed twenty times.

They may not understand the new rule yet.

But if they are climbing out, safety wins.

Do not keep an unsafe crib because the toddler seems too young for the freedom of a bed.

Instead, make the room safer and teach the new rule slowly.

What If My Toddler Has Not Climbed Out Yet?

If your child is only starting to pull up or put a foot on the rail, act early.

Check that the mattress is at the lowest approved level.

Remove large toys.

Remove anything that works like a step.

Read the crib manual.

Measure your child's height.

Start planning the next sleep setup.

You may have time to prepare before the first escape.

What If My Toddler Is Under 15 Months?

This needs extra care.

Under CPSC rules, a toddler bed is intended for children at least 15 months old.

If a child younger than that is escaping the crib, do not copy a random floor bed setup from social media.

Check the crib manufacturer's instructions.

Talk with your pediatrician about a suitable safe sleep setup.

The unusual age makes individual guidance more useful.

What If My Toddler Is 35 Inches but Never Climbs?

The height limit still matters.

HealthyChildren advises moving to another bed around 35 inches.

CPSC crib warnings also use 35 inches as a stop point.

You do not have to wait for climbing to begin.

What If the New Bed Ruins Sleep?

It may affect sleep for a while.

That does not mean you made the wrong safety choice.

Your toddler has new freedom.

They may test it.

Keep bedtime steady.

Keep naps as normal as possible.

Keep nighttime responses short.

If sleep becomes messy, compare the day with the Toddler Sleep Schedule by Age.

If the change also brings more waking, nap refusal, or bedtime battles, read the Toddler Sleep Regression Guide.

Should I Use a Sleep Sack to Stop Climbing?

A sleep sack can be normal sleep clothing when it fits well and is used as intended.

That is different from using one to stop a known climber from moving their legs.

Do not use clothing as a way to ignore the crib stop point.

If your toddler has begun climbing out, solve the sleep space problem.

Do not try to restrain the new motor skill.

Should I Turn the Crib Around?

I would not rely on this.

Some cribs have a taller back panel.

Parents sometimes turn that side toward the room to make climbing harder.

But crib use should follow the maker's instructions.

Once your child has begun climbing out or reached the product limit, furniture position does not cancel the safety rule.

What If My Toddler Fell While Climbing Out?

Check your child first.

Then fix the sleep setup before the next sleep.

Seek medical care after a fall if your child has signs such as:

• Loss of consciousness
• Repeated vomiting
• Seizure
• Worsening confusion
• Difficulty waking
• New weakness
• Problems walking
• Major bleeding
• Any symptom that worries you

For more help after a fall, see the Toddler First Aid Guide.

Common Mistakes After a Crib Escape

Waiting for another escape

The first successful climb already tells you the skill is there.

Adding a taller homemade barrier

Do not modify the crib unless the maker designed that option.

Using a crib tent

Do not replace a fall risk with an entrapment risk.

Moving to a bed but forgetting the dresser

The whole room matters now.

Using any bed rail that fits

Age, mattress fit, gaps, and current safety rules matter.

Changing the entire bedtime routine

Keep familiar parts of bedtime steady.

Turning every exit into attention

Keep the return calm and short.

Assuming age matters more than ability

A young climber still has a fall risk.

What Should You Do Tonight?

If your toddler is climbing out of the crib, do these things in order:

1. Check the crib instructions
2. Stop crib use if your child has begun climbing out or reached the crib limit
3. Set up an age appropriate sleep space
4. Anchor furniture
5. Protect windows and cords
6. Remove small and dangerous items
7. Check stairs and exits
8. Use the same bedtime routine
9. Return your toddler calmly if they get out

You can work on sleep habits over the next several nights.

The safety change comes first.

Conclusion: Make the Room Safe Before the Next Sleep

A toddler climbing out of crib is telling you the sleep setup has changed.

Do not turn it into a battle about obedience.

Do not wait for a fall.

Use the crib limits.

Make the room safe.

Choose the right next bed.

Keep bedtime familiar.

Your next step: check your toddler's crib manual and height today, then complete a room safety check before the next nap or bedtime.

Frequently Asked Questions About a Toddler Climbing Out of Crib

What should I do when my toddler starts climbing out of the crib?

Stop treating the crib as a safe container once your child begins climbing out. Check the crib instructions, prepare an age appropriate bed, childproof the entire bedroom, and keep the bedtime routine the same.

What is the 35 inch crib rule?

CPSC crib warning language says to stop using a crib when the child begins climbing out or reaches 35 inches, which is 89 cm. HealthyChildren gives the same height transition point.

Should I lower the crib mattress if my toddler is climbing?

The mattress should already be at its lowest approved setting before a child learns to stand. Lowering it helps before climbing out begins. It should not be used to extend crib use after a child has started escaping.

Is my toddler ready for a toddler bed?

Bed readiness is helpful, but safety comes first. If the crib has become unsafe because your child climbs out or reaches the height limit, prepare the next safe sleep space even if your toddler needs time to learn new bedtime rules.

Can I use a crib tent to stop my toddler climbing out?

Do not use an unapproved crib tent or homemade barrier as an escape solution. CPSC has recalled crib tents because of entrapment and strangulation hazards.

Are portable bed rails safe for toddlers?

They can be appropriate when they meet current safety rules, fit the mattress and bed correctly, and are used for the right age. CPSC says portable bed rails are intended for children who can get in and out of an adult bed without help, usually ages 2 to 5.

How do I stop my toddler from leaving the new bed?

Use a calm and consistent response. Walk your toddler back to bed, use a short bedtime phrase, and leave again. Keep the response the same each time and praise successful bedtime behavior in the morning.

Will moving from the crib ruin my toddler's sleep?

Sleep may become less steady for a short time because your toddler has new freedom. Keep naps, bedtime, and the bedtime routine as consistent as you can while the child learns the new boundary.
