Can a 3 year old sleep in a toddler bed?
Short answer: Yes, many children move to a toddler bed between about 18 months and 3 years, often once they climb out of the cot.
Babies change fast, so the answer depends on your child's age, weight and development, and on your product's instructions.
What the guidance says
- Use a firm, flat, waterproof mattress in good condition, with no raised or cushioned edges, that fits the cot or Moses basket with no gaps.
