Moving from a crib to a toddler bed: when and how

At what age should a child move from a crib to a toddler bed?

There's no fixed age: most children switch between 18 months and 3 years, once they start climbing. The main sign it's time to switch beds is a child who manages to get a leg over the rail, or has already done it once. The height of the rail won't stop them a second time. A fall from a crib, in a child who climbs, can happen head first. That risk, more than the age on the calendar, is what should trigger the decision. The American Academy of Pediatrics gives the same benchmark: it may be time for a toddler bed as soon as the child can climb out of the crib.

U.S. crib regulations use a numerical benchmark, detailed below: past 89 cm (35 inches), the rail no longer keeps a child of that size in. In practice, most children switch between 18 months and 3 years, often when several signs add up: the child climbs, asks for a "big bed," or the crib has to make room for a younger sibling. Climbing is the only sign that's truly pressing. The others can wait for the right moment.

Childproofing the room once the rail comes off

Before the first night in a bed without a rail, the room needs childproofing, since the child can now get up alone, at any hour, and explore a room they've only seen from someone's arms. Anchor tall furniture to the wall (dresser, bookcase): children like to climb on furniture, and the U.S. Consumer Product Safety Commission recommends anti-tip brackets. Remove curtain cords and electrical cables within reach, and put away anything that could cause injury in a fall or a bump against a piece of furniture's corner.

Curtain and blind cords deserve particular attention. Even tied high or fitted with a cord cleat, they remain dangerous: the same commission prefers cordless blinds and curtains, and advises keeping beds and furniture away from windows, preferably on a different wall.

If the room opens onto stairs or a hallway leading to a risky area, a gate at the door prevents unsupervised nighttime wandering. It takes over the role the crib rail played, moved to the room's entrance. For the very first nights, some parents put the mattress directly on the floor: that removes the risk of a fall from a bed frame while the child gets used to sleeping without bars.

Keeping the bedtime routine intact during the transition

The new bed changes the scenery, not the routine: same sequence of steps, same story, same time. Reusing the crib mattress and sheets for the first few nights, rather than replacing everything at once, keeps at least the familiar smell and feel while everything else is already changing.

Avoid timing this change with another upheaval: a move, starting school, a new sibling, potty training, giving up the nap. A child absorbs one change at a time better. Stacking several transitions at once makes each of them harder, including the bed switch.

What the first week looks like, evening after evening

The first week in a toddler bed often follows the same script: the bedtime routine goes as usual, then the child gets up once, twice, sometimes ten times. Take a typical evening: after the story and the cuddle, you tell the child to stay in bed until you come back to check on them. They come out of the room after ten minutes. You walk them back without comment, with the same words, and leave right away. They come back a third time: same gesture, same sentence.

The American Academy of Pediatrics advises keeping these exchanges brief and boring, praising the child when they stay in bed rather than when they get out, and telling them you'll look in on them during the night, which reassures some. The next morning, you praise them for sleeping in their own bed. The same source advises against letting them join the parents' bed: the new bed shouldn't become a path to the parents' bed (see co-sleeping).

What should I do if my child keeps getting up the first few nights?

Getting up several times a night the first week is common, not a sign the transition has failed. The response that works best is also the most boring: walk them back to bed calmly, with no discussion or negotiation, using the same words every time. The shorter and more predictable the exchange, the less reason the child has to try again.

The gate at the door, mentioned above, acts as a safety net during this period: it limits what the child can do alone at night without you having to step in each time they leave the bed. Allow one to two weeks before the nighttime outings become rare.

Two situations call for a different choice. If the outings continue well beyond those two weeks, or if the child puts themselves in danger by leaving the room, going back to the crib for a while is reasonable, rather than forcing a transition that isn't ready yet. And if the child keeps sleeping poorly with nothing changing, or you're worried about their tiredness during the day, talk to their pediatrician.

Should you wait a little longer?

Nothing requires switching beds as soon as a child reaches a certain age. A child who sleeps well in their crib, doesn't climb, and doesn't ask for anything can stay in it well past 2 or 3 years old without a downside. A slightly older child often finds the rule of staying in bed easier to understand, which can make the first nights simpler.
