Can I put the cot under a window?
Short answer: It is best not to. The Lullaby Trust says keep cots away from direct sunlight and blind cords, which are often near windows.
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.
- 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.
