Two Toddler Beds, Two Escape Artists: The Crib-to-Bed Transition With Twins
Move twins to toddler beds as late as you can, and only when a crib is actually being climbed. The staggered plan, the room-proofing for two loose toddlers, and the beds you may already own.
When should twins move from cribs to toddler beds? Later than you think, and only for a reason. A crib is a container. A toddler bed is a suggestion. With one child, opening the container means one small person wandering at 5am. With twins it means two small people who now have a co-conspirator, a shared room, and no adult present. Our verdict: keep both in cribs until one of them is genuinely climbing out, or until they are close to three, whichever comes first. Then move both within a couple of weeks, with the room prepped before the first night.
Why later is better with twins#
- Cribs are the last thing keeping two toddlers apart at night. Once both are loose in the same room, bedtime becomes a party they throw for each other. Every month of crib is a month of quieter evenings.
- Two children in beds need a room that is fully safe unsupervised, not mostly safe. That is real work (anchored furniture, covered outlets, nothing climbable near a window), and it is easier to do once, at a time you choose.
- The transition is worse when it is forced by a new baby needing the crib, a move, or a daycare change. If none of those are on the calendar, there is no prize for going early.
- Potty training is a separate reason people move early. In our experience a crib and a potty coexist fine for a while. Do not stack two transitions on one week unless you enjoy chaos.
The climber problem: move one, or move both#
The twin-specific decision arrives when one baby climbs out and the other does not. Three options, and we have a clear favorite.
- Move the climber only. Convert one crib to a toddler bed and leave the other baby in a crib. Cheap and fast. The catch is that the free twin will climb into the crib twin's space, or hand things over the rail. We have seen this last exactly two nights before the second conversion.
- Move both the same night. Cleanest for routine and for the room-proofing, and the twin who was not climbing tends to follow the other within days anyway. Our pick if the second twin is over two and the room is ready.
- Stagger by a week or two. Move the climber, watch what happens, then move the other. This works when the second twin is noticeably younger in development or is a much better sleeper you do not want to disturb yet. Set a date for the second move before you do the first.
Before any of that, try the cheap fixes on the climber. Lower the mattress to the lowest setting if it is not already. Turn a crib with a lower front around so the tall side faces out, if the manual allows it. Use a sleep sack with leg holes that still limits a big swing of the leg, like the Kyte Baby Sleep Bag Walker at around $70. None of these are permanent. All of them buy weeks.
Room-proofing for two loose toddlers#
A room that is safe for one wandering toddler is not automatically safe for two, because two toddlers can move things one cannot. Do this before the first night, not after the first 5am discovery.
- Anchor every piece of furniture to the wall: dressers, bookshelves, the changing table if it is still in there. Two toddlers can tip a dresser by opening all the drawers and climbing them together.
- Windows: cord-free blinds, locks or stops, nothing under the sill to stand on. Beds go away from windows.
- A gate at the bedroom door, not a closed door. The gate keeps them in the room you have made safe while leaving sightlines and airflow. Our gate-count guide covers which type.
- Strip the room down. Toys in a closed closet, lamps off nightstands, no cords in reach. Two toddlers at 5am will find the one thing you missed, together.
- Beds against opposite walls if the room allows. Six feet of distance is a surprising amount of friction for two toddlers who want to visit each other.
- Keep the monitor up. A two-camera system you already own is now watching two beds and a floor, and you will want the audio.
Beds: what to buy and what you already own#
- If you bought convertible cribs, this transition is close to free. The Graco Benton 4-in-1, DaVinci Kalani, and Babyletto Hudson all convert to a toddler bed with a conversion rail that costs somewhere around $30 to $60 per crib. Order both rails as soon as one baby starts climbing, before you need them.
- If you have non-convertible cribs like the Ikea Sniglar, a separate toddler bed for each twin runs from cheap to silly. Two crib mattresses on the floor with fitted sheets is a legitimate first step and costs nothing while you see how it goes.
- Keep the crib mattresses. A toddler bed conversion uses the same mattress, and each mattress stays with the child who has been sleeping on it.
- Two sleep sacks still. A walker-style sack keeps the bedtime cue that worked in the crib and slows the sprint to the door. Blankets can come later.
- Skip matching bed sets, guardrails on every side, and the character bed. A low bed with one rail on the open side is plenty.
The first two weeks#
Expect the bedtime routine to run twenty minutes longer and to involve a lot of returning children to beds without conversation. The rule that works for us: same routine as the crib, lights out, then every exit gets walked back silently. Two toddlers will test in shifts. Consistency in week one saves month two.
Naps are where it usually falls apart first, because daylight plus a friend is a strong offer. If naps collapse, keep the quiet time in the room with the gate up and accept that one or both may not sleep for a few days. They usually come back.
If one twin is clearly not coping and the other is fine, it is acceptable to put the struggling one back in a crib for a few weeks. Say it out loud as a plan, not a defeat, and set a date to try again.
What we'd do#
Keep both in cribs until one is truly climbing or they are approaching three. Lower the mattress, try the sleep sack, and buy yourself weeks. When it is time, room-proof completely, put a gate on the door, convert both cribs the same weekend, and run naps and nights identically. Two toddler beds are not the hard part. Two toddlers with freedom are, and the room does the parenting at 5am.

FAQ
- When should twins move from cribs to toddler beds?
- As late as you can. Keep both in cribs until one is genuinely climbing out or they are approaching three, whichever comes first. Cribs are the last thing keeping two toddlers apart at night, and every month of crib is a month of quieter evenings. Try lowering the mattress and a walker-style sleep sack first to buy weeks.
- If one twin climbs out of the crib, do both need toddler beds?
- Usually, and soon. Moving only the climber works for about two nights before the free twin is climbing into the other crib. Our pick is to move both the same night if the second twin is over two and the room is fully proofed. Staggering by a week or two is fine if one twin is clearly not ready, as long as you set a date for the second move.
- How do you room-proof for two toddlers in beds?
- Anchor every dresser and shelf to the wall, since two toddlers can tip what one cannot. Cord-free blinds and window stops, beds away from windows, lamps and cords out of reach, toys behind a closed closet door. Put a gate at the bedroom door instead of closing it, and keep the two-camera monitor running for audio.
- Do twins need new beds, or can convertible cribs work?
- Convertible cribs like the Graco Benton 4-in-1 or DaVinci Kalani turn into toddler beds with a conversion rail that costs somewhere around $30 to $60 each, using the same mattress. Order both rails when the first twin starts climbing. With non-convertible cribs, two crib mattresses on the floor is a legitimate free first step.
