Is it safe to put a cot in a loft or bay window?
Short answer: Keep the cot away from direct sunlight, radiators and blind cords, which are often near windows. Check the room stays at about 16C to 20C.
Here is the detail behind that answer, taken from current UK guidance from the NHS and the Lullaby Trust.
Things to check
- Check the internal size and buy a mattress that fits with no gaps.
- Adjustable base heights let you lower the mattress as your baby learns to sit and stand.
- Teething rails protect the top rails from little teeth.
What the guidance says
- Place the cot away from radiators, direct sunlight and blind cords.
