How Many Bassinet and Cot Sheets Do You Need?
When preparing for a new baby, it’s easy to focus on choosing the cot, mattress and nursery furniture. But one of the most practical questions parents often ask is surprisingly simple:
How many bassinet and cot sheets do you actually need?
Babies spend a lot of time sleeping in their first year, and bedding changes can happen more often than expected. Having enough sheets on hand helps keep your baby’s sleep space clean, comfortable and easy to manage during those middle-of-the-night changes.
How Many Bassinet Sheets Do You Need?
Most parents find that 2–3 fitted bassinet sheets is a good starting point.
Newborns often experience:
-
milk spills
-
reflux or spit-up
-
nappy leaks
-
drooling
Because bassinets are used frequently during the newborn stage, sheets may need to be changed regularly.
A practical bassinet bedding setup
A simple and effective bedding setup is:
-
2–3 fitted bassinet sheets
-
1–2 waterproof mattress protectors
This allows you to quickly swap out bedding while the other items are being washed.
How Many Cot Sheets Do You Need?
Once your baby moves from the bassinet to the cot, you’ll likely need a similar number of sheets.
Most families find 2–4 cot fitted sheets works well.
Cot sheets may need changing due to:
-
overnight nappy leaks
-
spills or drool
-
general laundry cycles
Having several sheets available ensures you always have a clean one ready when needed.
A typical cot bedding setup
Many parents keep:
-
2–4 fitted cot sheets
-
1–2 mattress protectors
This makes it easy to layer bedding and quickly refresh the sleep space.
The Layering Trick Many Parents Use
A simple tip that many parents find helpful is layering bedding.
Some parents prepare the mattress like this:
-
mattress
-
waterproof protector
-
fitted sheet
-
second protector
-
second fitted sheet
If an accident happens overnight, you can remove the top layer quickly and the bed is already prepared underneath.
Why Well-Fitting Sheets Matter
In Australia, safe sleep guidance recommends that bedding should be firm fitting and secure, with no loose fabric in the sleep space.
Well-fitting fitted sheets help ensure:
-
a smooth sleep surface
-
no loose or excess fabric
-
bedding that stays securely in place
This is especially important for bassinets or specialty mattresses such as oval bassinets and Stokke Sleepi beds, where standard sheets may not fit correctly.
Custom fitted sheets designed for specific mattress shapes can help ensure the best fit.
What About Pram Bassinet Sheets?
If your pram includes a bassinet attachment, you may also want spare bedding for this sleep space.
Pram bassinets are often used for:
-
newborn naps
-
walks
-
travel
Just like home bassinets, the mattress can occasionally need cleaning.
Many parents find it helpful to have:
-
1–2 fitted pram bassinet sheets
-
a waterproof protector or liner
This helps keep the pram mattress clean and fresh.
A Simple Bedding Checklist
If you're setting up a nursery, a practical starting point is:
Bassinet
-
2–3 fitted sheets
-
1–2 mattress protectors
Cot
-
2–4 fitted sheets
-
1–2 mattress protectors
Pram bassinet
-
1–2 fitted sheets
-
1 waterproof liner or protector
This provides enough bedding to handle everyday spills and laundry cycles.
Keeping Your Baby’s Sleep Space Comfortable
Babies spend many hours sleeping, especially during the newborn months. Having enough well-fitting sheets and mattress protectors makes it much easier to keep their sleep space clean and comfortable.
Choosing bedding that fits the mattress securely — particularly for specialty shapes like oval bassinets or pram mattresses — helps maintain a smooth and safe sleep surface.
A small collection of spare sheets can make a big difference when those inevitable little messes happen.
