Can a newborn sleep in a cot bed?
Short answer: Yes. Most cot beds are suitable from birth with the base in its highest position. Keep it clear and in your room for at least the first 6 months.
Here is the detail behind that answer, taken from current UK guidance from the NHS and the Lullaby Trust.
Things to check
- Check the mattress size listed for the frame. 140 x 70cm is common, but not universal.
- Keep every conversion panel, bolt and instruction sheet for the toddler-bed stage.
- Look at adjustable base heights, teething rails and any matching furniture.
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.
- Keep the cot clear: no pillows, duvets, cot bumpers, loose blankets, soft toys, pods, nests, wedges or anything to keep your baby in place.
