When to switch from crib to toddler bed? Most children make the move somewhere between 18 months and 3 years, and many experts suggest waiting until closer to age 3 if your child is sleeping well and staying safely in the crib. The two clearest signals that it is time sooner are height and climbing: the American Academy of Pediatrics suggests moving to a bed once a child is about 35 inches (89 cm) tall, or as soon as they start climbing out of the crib.

There is no prize for switching early. A crib keeps a toddler contained, which makes bedtime simpler and nights safer. Below we cover the signs that it is time, the signs that it is not, how to prepare the room, and a gentle plan for the first few weeks.

Clear Signs It Is Time to Make the Move

These are the situations where the question of when to switch from crib to toddler bed tends to answer itself:

• Climbing out: if your child has climbed out, or is clearly trying, a fall from crib-rail height is a bigger risk than the transition.
• Height: once your child is around 35 inches tall, the crib rail no longer reaches high enough relative to their body, even on the lowest mattress setting.
• Potty training at night: a child who needs to get to the bathroom independently needs a bed they can safely get in and out of.
• Your child asks for it: some toddlers are genuinely excited about a “big kid bed,” which can make the move easy.

The AAP’s guidance on moving from crib to bed highlights the height and climbing signals in particular, since they are about safety rather than preference.

Signs It Is Better to Wait

Just as important as knowing when to switch from crib to toddler bed is knowing when not to. If your child sleeps well, stays in the crib, and is under 35 inches, there is usually no reason to rush. A few situations make waiting especially sensible:

• A new sibling is on the way. If you need the crib for the baby, move the toddler at least a couple of months before the birth, or wait until a few months after, so the change does not feel like being pushed out.
• Other big changes are happening. Starting daycare, moving house, or a family upheaval are already a lot for a toddler. One change at a time is easier.
• Sleep is already rocky. If your child is going through a regression or illness, wait until things settle.

Typical Timeline at a Glance

Use this table as a rough guide to when to switch from crib to toddler bed at different ages.

Age	What Usually Happens	Recommended Approach
Under 18 months	Rarely ready; impulse control is still very limited	Keep in crib, lower the mattress fully
18–24 months	Some children start climbing	Switch only if climbing out or very tall
2–3 years	Most common transition window	Switch when signs appear and life is calm
3 years +	Better able to understand “stay in bed” rules	Often the smoothest time to switch

Toddler Bed, Convertible Crib, or Twin Bed?

Once you know when to switch from crib to toddler bed, the next question is which bed. A toddler bed uses the same mattress as a standard crib, sits low to the ground, and usually has small side rails. That familiarity can make the transition feel less dramatic. Convertible cribs often turn into a toddler bed by removing one side and adding a rail kit, which saves money and space. Our guide on how long you use a convertible crib explains how those stages work.

Some families skip the toddler bed and go straight to a twin bed placed low or on the floor, with a guard rail. That can be a better long-term value, though a larger bed can feel less cozy for a small child at first.

Make the Room Safe Before the First Night

A child in a bed can get up and explore at night, so the whole bedroom effectively becomes the crib. Go through the room at your child’s eye level before the switch:

1. Anchor furniture to the wall. Dressers, bookcases, and TVs can tip when climbed. The U.S. Consumer Product Safety Commission’s Anchor It campaign explains how to secure them.
2. Cover outlets and secure cords. Window blind cords and charging cables should be out of reach.
3. Lock windows. Use window stops or guards so windows cannot open far enough for a child to fall.
4. Use a guard rail and a low bed. Keep the mattress close to the floor and add a rail on any open side.
5. Consider a door gate. A gate at the bedroom door keeps a wandering toddler from reaching stairs at night.

These checks matter more than the exact date you pick for when to switch from crib to toddler bed, because a safe room is what lets the change go well.

A Gentle Plan for the First Few Weeks

Whatever you decide about when to switch from crib to toddler bed, keep everything else about bedtime the same. Use the same routine, the same lovey, the same sound machine, and the same bedtime. Many parents put the new bed in the same spot the crib was, so the room looks familiar. Talk about the bed beforehand, let your child help pick sheets, and practice “lying down in the big bed” during the day.

Expect some testing. Many toddlers get up repeatedly the first few nights simply because they can. Calmly walk them back to bed with as little conversation as possible, every time. A simple visual rule, such as a toddler clock that changes color when it is okay to get up, can help older toddlers understand when morning starts.

A Practical Scenario: Two Different Toddlers

Picture a 20-month-old who has started hoisting one leg over the crib rail. Even though the child is young, the climbing changes everything. For that family, the answer to when to switch from crib to toddler bed is “now,” along with a quick room safety check and a low bed with rails.

Now picture a 2.5-year-old who sleeps 11 hours, never tries to climb, and has a sibling arriving in a month. For that family, waiting makes more sense. Keeping the toddler in the crib for now and planning the move a few months after the baby arrives avoids stacking two big changes together.

Frequently Asked Questions

When to switch from crib to toddler bed: is there a best age?

There is no single best age, but many children do best between 2.5 and 3.5 years, when they can understand simple rules about staying in bed. Switch earlier if your child climbs out or reaches about 35 inches tall.

Is 18 months too early for a toddler bed?

For most children, yes, unless they are climbing out of the crib. Younger toddlers usually lack the impulse control to stay in an open bed.

What if my toddler keeps getting out of bed?

Stay calm and consistent. Return them to bed quietly each time without extra attention. Most toddlers settle within a week or two if the response is predictable.

Should I lower the crib mattress instead?

Yes, if you have not already. Lowering the mattress to the bottom setting can buy months before a switch is needed, as long as your child is not climbing out.

Can a toddler use a pillow and blanket in a toddler bed?

Many pediatric sources suggest introducing a small, flat pillow and light blanket after age two at the earliest. Until then, a wearable blanket remains a good option.

Final Thoughts: When to Switch From Crib to Toddler Bed?

When to switch from crib to toddler bed? For most families, somewhere between 18 months and 3 years, with many children doing best closer to 3. Move sooner if your child climbs out or reaches about 35 inches tall, and hold off if a new sibling or other big change is coming. Prepare the room as if the whole space were the crib, keep the bedtime routine identical, and respond calmly to the first-week testing. Handled that way, the move to a big kid bed becomes a milestone to celebrate rather than a battle at bedtime.
