One of the biggest milestones in toddlerhood is moving from the safety of a cot to a big kid bed. But like many parenting transitions, it can feel overwhelming. How do you know when your little one is ready? Will it disrupt their sleep? Should you wait as long as possible or dive in early?
As an infant and toddler sleep consultant, I’ve helped many families navigate this exact change—and I’m here to help you do it smoothly and confidently.
When Is the Right Time to Make the Move?
There’s no universal "perfect age," but most toddlers are ready to transition between 2.5 and 3.5 years old. Some may need the change earlier, while others benefit from staying in the cot a little longer.
Here are some signs your toddler may be ready:
They’re climbing out of the cot (safety first!).
They’re toilet training and need easy night time access to the bathroom.
They’re asking for a bed or showing interest in “big kid” sleep spaces.
They're outgrowing their cot.
If none of these are happening yet, there’s no rush. In fact, staying in the cot can help maintain better sleep for longer—especially if your toddler still feels secure in it.
Common Mistake: Transitioning Too Soon
Many parents are tempted to make the switch around a new sibling’s arrival or just after a sleep regression. But be cautious: moving too early can backfire. If your child isn’t developmentally ready, the change can lead to bedtime battles, frequent night wakings, and early morning starts.
Unless safety is a concern, I often recommend waiting until your toddler is closer to 3 years old, when they better understand boundaries and instructions.
How to Make the Transition Smooth
Here are some sleep consultant-approved tips to make the process easier:
Talk about the change in advance. Read books together about moving to a big bed. Get your toddler involved in picking bedding to make it exciting and to make them feel involved in the process.
Keep the bedtime routine exactly the same. The only thing that should change is the sleep space—consistency helps toddlers feel safe and secure.
Use a bed rail or keep the mattress low. This helps mimic the enclosed feeling of the cot and prevents falls.
Set clear boundaries. Toddlers love to test limits. Make expectations around staying in bed clear, and stick to them gently but consistently.
Be patient. It’s common for sleep to wobble during the transition. Offer lots of reassurance but try not to introduce new habits you don’t want to keep.
Need Personalized Support?
Every child is different. If you're feeling unsure about the timing or your toddler is already struggling with the transition, you don’t have to navigate it alone. I offer personalised sleep support to help make these changes smoother for both you and your child.
