The right time to move a child to a toddler bed is when they show readiness signs, not when they reach a specific age. A toddler bed is a small bed frame designed for children transitioning from a cot, using a toddler mattress and sitting low to the ground to minimise fall risk.
For Australian parents, the cot-to-bed transition can feel big, but good timing and a familiar setup make it smoother. This guide covers readiness signs, safe setup, what to buy, and common timing mistakes.
Signs Your Child Is Ready For a Toddler Bed
The clearest sign is climbing. If your child can climb out of the cot, it is time to move. A fall from the top of a cot rail is a bigger risk than sleeping in a low toddler setup, so the bed change becomes a safety decision, not just a milestone.
Height is another useful signal. Many cot manufacturers recommend moving on when a child reaches around 90cm tall because the cot rail may no longer offer enough containment. Age still matters, but it should not be the only guide. Most Australian children make the move between 18 months and 3 years.
Do not rush the change before 18 months unless there is a clear safety concern. Younger toddlers often still benefit from the secure boundary of a cot. If your child is asking for a "big kid bed" because of an older sibling, that motivation can help. A child who wants the change often adjusts more calmly than one who moved too early. You can browse Boori convertible cots and check whether your model can move into the next stage.
When To Wait: and Common Timing Mistakes?
If a new baby is due within 2--3 months, move your toddler well before the baby arrives or wait until 2--3 months after. Changing the bed at the same time as a new sibling can make your toddler feel displaced, especially if the cot is suddenly needed for the baby.
House moves, starting childcare, toilet training and major routine changes can also affect sleep. If the cot is safe and your child is settled, wait until routines feel calmer. A child happily sleeping in a cot at 2.5 years does not need to move yet.
The biggest mistake is moving too early because the bed has already been bought. Children under 18 months often do not understand the boundary of an open bed. If you do need the cot for a sibling later, plan the timeline early. Boori's conversion options can help families convert your Boori cot to a toddler bed without making the change feel like a sudden loss.
How to Set Up the Toddler Bed: Safety and Environment?
Place the toddler bed against a wall and use a guard rail on the open side. This reduces fall risk and gives a sense of enclosure similar to the cot. The aim is to make the new sleep surface feel secure and familiar.
Where possible, keep the mattress low. Boori convertible cots can move into toddler mode using model-specific parts. Always follow the model instructions, use the correct hardware and avoid mixing generic rails or fixings with a Boori cot.
Keep everything else the same for the first week. Use the same room, same bedtime rhythm, same comfort items and familiar bedding where possible. The bed should be the only major change. Australian cot safety is linked to AS/NZS 2172, while Red Nose Australia supports firm, flat sleep surfaces with no unsafe loose items.
Room-proofing becomes essential once your child can get out of bed alone. Secure furniture to walls, cover power points and remove climbable hazards. If needed, use an adult-height door latch and safety-check nearby areas.
What to Buy: Mattress, Guard Rail and the Transition Itself
A firm, flat toddler mattress is essential. The standard Australian toddler mattress size is usually 130cm × 70cm. If the existing cot mattress fits, stays firm and remains clean, you may not need a new one.
The guard rail should match the bed or cot model. For Boori convertible cots, use the correct toddler guard panel or conversion kit for that exact model. A rail that looks close enough is not enough because attachment points and fit matter.
Fitted sheets should stay secure on the mattress without loose fabric. Standard single sheets are too large for a toddler mattress, so choose bedding made for the size. Boori's toddler bed sheets and bedding can help keep the sleep surface neat and familiar.
Introduce the bed gradually. Let your child explore it during the day, read stories on it and try a nap before the first overnight sleep. If your child is close to outgrowing the toddler stage, explore kids' bed frames for the next stage as well. You can also find the right toddler mattress if the existing cot mattress no longer suits.
FAQ
What age should a toddler move to a bed?
A toddler should move to a bed when they show readiness signs, not at one fixed age. The clearest signs are climbing out of the cot, reaching around 90cm tall, or consistently asking for a big bed. Most Australian children transition between 18 months and 3 years.
Do I need a guard rail for a toddler bed?
Yes, a guard rail on the open side is strongly recommended for children under 3. It helps reduce falls during sleep and gives a familiar sense of enclosure after the cot. Boori convertible cot setups should use the correct model-specific toddler guard panel.
How do I stop my toddler climbing out of bed after the transition?
Use a consistent bedtime routine, keep the room dark and calm, and return your child to bed without turning it into play. If your child repeatedly leaves the room, an adult-height door latch may help, but nearby areas must be safety-proofed first.
Can I convert my Boori cot to a toddler bed?
Many Boori cots are convertible and can move from cot to toddler bed using a model-specific conversion kit or toddler guard panel. Check your Boori model number before buying parts. Using the correct Boori hardware helps keep the converted setup secure and suitable.
What mattress size does a toddler bed use in Australia?
A toddler bed in Australia commonly uses a 130cm × 70cm mattress, which is also a common cot mattress size. If your cot mattress is firm, flat, clean and still fits the toddler configuration correctly, you may be able to keep using it.
Is a toddler bed necessary, or can I go straight to a single bed?
A toddler bed is helpful but not essential, because some children move straight to a single bed with a guard rail. Toddler mode can feel easier because it keeps the same mattress size, sits lower to the floor and feels more familiar after the cot.
How long does a child use a toddler bed?
Most children use a toddler bed from around 18 months to 3 years until about age 5--7. Some Boori convertible cot systems can extend the furniture's useful life further through later stages, depending on the model and available conversion parts.
Summary
Move to a toddler bed when your child shows readiness signs: climbing out, reaching around 90cm, or clearly asking for a big bed. Set the room up with a firm mattress, secure guard rail and room-proofed environment.
