What bedding goes in a toddler bed?
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 the mattress size it takes and buy a mattress that fits snugly.
- Side guards help stop your child rolling out in the early weeks.
- A low height makes it easier to climb in and out on their own.
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.
