Can a 6 week old sleep in a cot bed?
Short answer: Yes. A cot bed with a firm, flat mattress is suitable from birth, in your room for at least the first 6 months.
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
- The NHS advises placing your baby in a separate cot or Moses basket in the same room as you for every sleep, day and night, for at least the first 6 months.
- 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.
