The Cot-to-Bed Transition

This transition is not for the faint of heart! 

Moving your little one from a cot to a big bed is a major milestone—and one that doesn’t always come with smooth sailing! This transition can be tricky, especially when your bub is still developing impulse control, which typically matures between 2.5 and 3 years of age.

Unless your child is climbing out of their cot or there’s a safety concern, it’s often best to hold off on the transition until they’re closer to that age range.

Not sure if it’s time? Here are some common signs your toddler may be ready:

• They’re climbing on or out of their cot

• They’re close to the cot’s weight limit

• They have little room to move comfortably in the cot

• They’re asking for a big bed or refusing the cot

• They’re around 3 years old

• They’re starting to show signs of impulse control

• They’re toilet trained and need to get to the toilet independently

The first step? Build positive anticipation. Let your little one help choose their new bed linen or a special pillow. Talk about the change with enthusiasm and reassurance—it’s a big deal for them, and your excitement sets the tone.

Plan the switch for bedtime, not nap time. Sleep pressure is higher at bedtime and melatonin levels (the body’s natural sleep hormone) are also at their peak—this makes it easier for your child to settle. Try to avoid transitioning on a day when your little one is overtired or hasn’t had a proper nap, as this can make settling much harder.

Stick to your usual wind-down routine so all of their familiar sleep cues remain consistent. When it's time for bed, calmly let your child know it's time for sleep—just like any other night.

If your child gets up and out of bed or follows you out of their room, silently return them to their bed. Keeping the return silent is key here as even negative attention is still attention and can reinforce this behaviour. 

Since your child is now more mobile in their room, this is also the time to double-check safety. Make sure furniture is secured to the wall, cords are out of reach, and nothing dangerous is within easy access. You might also consider a bed rail for extra safety and security during the first few weeks.
