A 28-month-old still does best on one nap of 60–120 minutes around 12:00–1:00 PM, wake windows of 5–6 hours, and an 11–12 hour night starting between 7:00 and 8:00 PM. That schedule is largely held together by one piece of furniture. A crib is a physical boundary; a bed is a suggestion — and a toddler who can leave the room has, in their own view, been handed the keys to the house.
The nap is the first casualty of an early move. A 28-month-old who can walk out of the room at 12:30 PM generally will, and a lost nap at this age costs an early bedtime, a rough evening, and often an early wake. Then bedtime itself becomes an hour of returns. So the default is to wait — usually until close to 3 — unless safety forces the issue. Below: why waiting works, the one real exception, and how to do it well if the exception applies to you.
Why waiting until ~3 usually goes better
Around 3, three things arrive that make a bed workable: enough impulse control to stay put when they'd rather not, enough language to hold a rule in mind after you've left, and enough understanding for tools like a bedtime pass to work. At 28 months those are all half-built. Moving now typically costs 30–60 minute bedtimes, wandering at 2 AM, and a nap that vanishes for weeks.
The climbing-out exception: if your toddler climbs out confidently and repeatedly with the mattress on its lowest setting and a sleep sack hasn't stopped it, safety wins — a fall from a crib rail is the worse outcome, and you move now.
The sibling exception is usually not one: a newborn spends months in a bassinet, and a second-hand crib costs far less than a lost nap. Give the toddler the crib and buy the baby time.
If you must: how to do it
- Same layout. Put the bed where the crib was; keep the same wall, same nightlight, same sound machine. Change one thing, not the room.
- The room becomes the crib. Anchor furniture, secure cords and blinds, and use a gate at the door so a toddler who wanders finds a safe room, not the stairs.
- Same routine, same words. Nothing else about bedtime changes that week.
- Rehearse in daylight: "This is your bed. At bedtime you stay in it until morning." Practise lying down, practise staying.
- Boring returns. When they get up, walk them back silently — no talking, no eye contact, no negotiation — every single time. Night one might be twenty returns; night four is usually two.
- The nap happens in the bed too. Same rules, same returns.
- Don't stack it with potty training or a new baby in the same month. Expect 1–2 weeks to settle.
