Cot Sheets

The standard size dimensions for a cot mattress in Australia are 130cm x 69cm.

Most cot manufacturers adhere to the agreed standard within a 1-2cm variance.

There are some brands however who make their cots significantly larger than standard sizing - check the Product Safety Sticker on your cot to find the recommended mattress size.

A well-fitted sheet should fit snugly on the mattress, so it doesn't slide off or get tangled as baby sleeps.

With fully elasticised corners to keep their shape, many fitted sheets are made from fabric that can stretch to fit mattresses of any shape, including oval, round or rectangle.

Fitted cot sheets also allow for the depth of the mattress, which can be between 10-20cm. If the cot mattress is slightly smaller than the sheet, any excess fabric can be pulled tightly under the mattress to avoid the sheet slipping or bunching and ensure a snug fit.

The number of cot sheets you need depends on how often you plan to change them and how frequently your baby experiences accidents.

Generally, having 2 to 4 sheets is recommended. Two sheets allow for one to be in use while the other is being washed, while additional sheets offer extra convenience for quick changes due to spills or leaks.

If you anticipate frequent messes, more sheets will save time and stress during laundry cycles.

Alternatively, if you layer two waterproof sheets over each other on the mattress, when the inevitable happens you won’t need to search for a clean sheet, strip the linen and remake the cot. Simply take off the soiled top sheet to reveal a fresh and clean one underneath. Doubling up your waterproof sheets is a great way to make middle of the night sheet changes much easier!

When choosing fabric for a baby cot sheet, consider these key factors:

Breathability - cotton (especially organic cotton and muslin) as well as bamboo are popular choices due to their breathability, helping to keep baby cool and comfortable

Softness - jersey cotton is soft and stretchy (like a t-shirt) and is ideal for sensitive baby skin

Durability - woven cotton offers durability and structure

Waterproofing - consider waterproof sheets if you want extra protection against spills and leaks

Hypoallergenic properties - organic fabrics are often hypoallergenic, with bamboo also antibacterial and absorbent, making them ideal for babies with sensitive skin
