Is a cot bed safe for a newborn?
Short answer: Yes, if it is designed for use from birth and used as the instructions say. 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).
- 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
