When to move from a crib to a toddler bed: the 35-inch rule (2026)

Short answer: move your child to a bed when they’re about 35 inches (89 cm) tall, or when the crib’s side rail is less than three-quarters of their height (about nipple level), because the most common crib falls happen during climb-outs (AAP). Before then, lower the mattress to its lowest position by the time your baby can stand.

Recalls checked November 10, 2026 on CPSC. We searched CPSC recalls with “toddler bed” in the title announced since November 1, 2025 and found none on November 10, 2026. We also checked dresser recalls because a toddler’s room needs anchored furniture: 41 dresser tip-over recalls in that window. Our recall-check policy.

Quick answer

There is no set age for the switch; the AAP’s[1][2][3] cue is height and climbing. Moving a toddler out of the crib also turns the bedroom into a play space they can roam at night, so baby-proofing matters as much as the bed.

Twin bedLow frame helps; keep it away from windows and cords

How do I baby-proof the room for a toddler in a bed?

The AAP[1][2][3] says about half of fatal furniture tip-overs happen in bedrooms, sometimes when parents think kids are asleep, so anchor dressers and TVs before the switch. Keep the bed away from windows, open windows from the top or use window guards (a screen won’t stop a fall), and don’t put anything a child can climb in front of a window (AAP). Keep blind and curtain cords out of reach.

Who should skip this, and what to skip

Skip buying a toddler bed if you have a convertible crib with a toddler kit or are happy with a mattress on the floor, which the AAP[1][2][3] suggests for children who might fall.

  • Moving to a bed early “to make room” while your child still fits the crib: The AAP’s[1][2][3] cue is height and climbing, not age; a crib is the contained option until then.
  • Crib tents or add-on “climb-proof” covers: Our sources don’t support them, and the AAP[1][2][3] says the safe crib holds only a fitted sheet.
  • Bunk beds for a toddler: Our sources don’t cover them; a low bed or floor mattress matches the AAP’s[1][2][3] advice on falls.

Everything we tell parents to skip

The free or budget option

The AAP’s[1][2][3] mattress-on-the-floor option is free and uses the crib mattress you already own. Spend the money instead on metal anchor kits for the dresser and TV in that room (about $5 to $25 each, AAP).

Frequently asked questions

What age do kids switch to a toddler bed?
The AAP[1][2][3] uses height, not age: about 35 inches (3 feet), or when the rail is below three-quarters of their height.
My toddler climbs out but is under 35 inches. What now?
The AAP[1][2][3] says the most common falls happen when a child tries to climb out, which is its signal to move to another bed. Keep the crib mattress at the lowest position until then.
Do toddler beds have to meet a safety standard?
Yes, 16 CFR part 1217 for toddler beds made or imported since October 20, 2011.
Should I keep the crib for a new sibling?
Check it against current crib rules and recalls first; see how to choose a safe crib.

How to choose a safe crib (2026): standards, used cribs and setup

Short answer: buy a crib that meets the 2011 federal crib standard (any new crib sold in the US must), with fixed sides, slats no more than 2⅜ inches apart, no cutouts or tall corner posts, all its hardware and instructions, and no recall. Avoid drop-side, antique and pre-2011 cribs.

How to anchor furniture and TVs to prevent tip-overs (2026)

Short answer: anchor every dresser, bookcase, TV and piece of furniture with drawers, doors or shelves to the wall, and mount or strap TVs. The AAP says anti-tip devices cost about $5 to $25 and take minutes; it suggests metal anchors into a stud. A newer dresser that meets the 2023 federal stability rule still needs anchoring.

Are crib bumpers safe? The ban, mesh liners and braided bumpers (2026)

Short answer: no. Padded crib bumpers, vinyl bumper guards and slat covers are banned under the Safe Sleep for Babies Act, and CPSC recalled two brands in the past year for violating the ban. Non-padded mesh liners aren’t banned, but the AAP says they aren’t needed and can come loose. A bare crib with a fitted sheet is the safe setup.
