How to Transition from a Cot to a Big Kid Bed Smoothly

Moving your child from a cot to a big kids bed is a significant milestone—for both parents and children. While it can be an exciting time, it’s also common to face a few challenges.

The key to a smooth transition is planning ahead and approaching the change with patience and understanding. Below is a practical guide to help make the switch as seamless as possible.

Know When It’s Time to Make the Change

There’s no exact age when children need to move from a cot to a bed, but most make the transition between 18 months and 3½ years. Look out for signs that your child may be ready:

  • They’re climbing out of the cot or attempting to

  • They’re too big for the cot and appear cramped

  • They’re showing interest in “big kid” things or copying older siblings

  • They’ve begun toilet training and may need to get out of bed independently

Avoid major life changes (such as moving house or welcoming a new sibling) when making the transition, unless the new bed is part of the excitement.

Involve Your Child in the Process

Making your child part of the decision can help them feel a sense of ownership and excitement about the new bed.

  • Let them choose the bed frame or colour (from parent-approved options)

  • Involve them in picking out new bedding or a special comfort item

  • Talk positively about the change to build enthusiasm

When children feel included, they’re more likely to approach the shift with confidence and curiosity rather than fear.

Choose the Right Bed for the Transition

Not all “big kid” beds are created equal. Choosing the right bed makes a world of difference in how secure and comfortable your child feels.

  • Consider a toddler bed as a midway option—these are low to the ground and often use the same mattress from the cot

  • Alternatively, opt for a single or king single bed with safety rails

  • Look for beds with rounded edges and a sturdy, low-profile frame

Stick with breathable, firm mattresses that support your child’s posture and align with Australian safety standards.

Create a Comfortable and Familiar Sleep Environment

Even if the bed is new, the sleep space should still feel familiar. Aim to keep the environment calm and consistent.

  • Use the same nightlight, comforter, or white noise machine

  • Maintain the same bedtime routine (bath, story, cuddles)

  • Keep the layout of the room as similar as possible, so it doesn’t feel like a drastic change

Reassurance comes from the consistency of the bedtime rituals and sensory cues your child already knows.

Use Bed Rails or a Floor Mattress for Safety

It’s common for children to roll around in their sleep, especially when they’re adjusting to more space. Bed rails offer peace of mind and prevent falls.

  • Install temporary guard rails on either side of the bed

  • Alternatively, place a soft mattress or pillows on the floor beside the bed

  • Opt for beds that sit close to the ground to reduce injury risk

These measures can help prevent bumps and bruises while your child learns to navigate their new sleeping arrangement.

Be Patient and Expect Some Resistance

Even if your child was excited at first, the novelty can wear off. They might get out of bed more often, take longer to settle, or resist naps.

  • Stay calm and consistent with expectations

  • Walk them back to bed with minimal fuss if they wander out

  • Offer praise and rewards for staying in bed through the night

It might take a few weeks for them to adjust, so patience is key.

Encourage Independence While Offering Reassurance

Transitioning beds isn’t just about sleeping in a new space—it’s also a step toward greater independence. Balance this with gentle encouragement.

  • Let them practise getting in and out of bed during the day

  • Remind them that their bed is their special place where they can feel safe and cosy

  • Offer extra cuddles if needed, especially in the early days

If night waking or clinginess increases, it’s usually temporary. Provide reassurance, but avoid reverting to the cot unless it’s necessary for safety reasons.

Keep Bedtime Consistent and Predictable

One of the best ways to ensure a smooth transition is by sticking to a predictable routine. Children thrive on structure.

  • Keep bedtime and wake-up times consistent every day, including weekends

  • Limit screen time before bed and opt for calming activities instead

  • Use a visual bedtime chart if your child responds well to routines

The more predictable bedtime feels, the easier it is for your child to settle into their new sleeping environment.

Don’t Rush the Process

Every child is different, and some may need more time than others. Rushing the move can lead to stress or disrupted sleep.

  • Watch for cues that your child is truly ready

  • Trial naps in the new bed before switching fully, if needed

  • Keep the cot set up for a few weeks as a backup (if you’re unsure or expecting resistance)

Give your child the time they need to adjust emotionally and physically to the change.

Celebrate the Milestone

Making the switch to a big kid bed is a major step in your child’s development—celebrate it!

  • Take a photo of their first night in the new bed

  • Talk proudly about how grown-up they are

  • Use a reward system or sticker chart for staying in bed all night

Positive reinforcement builds confidence and makes the whole experience feel fun and empowering.

By planning carefully, involving your child, and staying patient throughout the process, you’ll lay the groundwork for smoother bedtimes and better sleep—for everyone.
