Can a 2 year old sleep in a cot bed?
Short answer: Usually, yes, until they start climbing out. Then convert the cot bed to a toddler bed.
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.
