What bedding goes in a bedside crib?
Short answer: The Lullaby Trust says a baby needs just two items in their cot: a firm, flat, waterproof mattress and lightweight bedding. Use a fitted sheet in the right size and either a well-fitted sleeping bag or firmly tucked-in lightweight blankets.
- Check it is made to BS EN 1130:2019.
- Make sure the fixing straps suit your bed frame and leave no gap between the crib and your mattress.
- Check the maximum weight and stage limits in the instructions.
What the guidance says
- The Lullaby Trust says a baby needs just two items in their cot: a firm, flat, waterproof mattress and lightweight bedding.
- If you use sheets and blankets, tuck them in firmly no higher than shoulder height. One blanket doubled over counts as two.
- A well-fitted baby sleeping bag is an alternative to blankets. Most makers base suitability on weight (usually around 4kg) rather than age, so check the label.
- Keep the cot clear: no pillows, duvets, cot bumpers, loose blankets, soft toys, pods, nests, wedges or anything to keep your baby in place.
