Can a 6 month old sleep in a cot bed?
Short answer: Yes. Lower the base before your baby can sit, kneel or pull up, as the instructions say, and keep the cot clear.
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.
- Keep the cot clear: no pillows, duvets, cot bumpers, loose blankets, soft toys, pods, nests, wedges or anything to keep your baby in place.
- Always place your baby on their back to sleep, in the feet-to-foot position (feet at the bottom of the cot, Moses basket or pram).
