Where should I put the cot in the nursery?
Short answer: Away from radiators, heaters, direct sunlight and blind cords, and somewhere you can reach easily.
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
- Place the cot away from radiators, direct sunlight and blind cords.
- Never use a hot water bottle or electric blanket, and do not place the cot next to a radiator, heater or fire, or in direct sunlight.
