Reusable fleece or disposable nappy liners?
Practical guide to cloth nappies
A liner is a thin layer placed next to your baby's skin, above the absorbent part of a cloth nappy. It helps catch stools and makes changes easier. A reusable fleece liner and a disposable liner suit different routines, and you can use both.
Liner and insert: two different jobs
The insert absorbs urine. It may be made of bamboo, cotton or microfibre. The liner goes on top of the insert or the built-in absorbent layer, directly against the skin. Adding a liner does not increase absorption. If the insert is saturated, adjust the absorbency instead.
Reusable fleece or disposable: what changes?
Reusable fleece liner
Microfleece lets urine pass through to the insert and can leave a drier feel against the skin. It often stays in place better with runny stools, especially during exclusive breastfeeding. It can be useful overnight or if your baby dislikes feeling wet. Wash and reuse it with the nappies. A wet bag makes it easier to carry a used liner home, and sticky stools may require rinsing.
Disposable liner
A thin single-use sheet, often sold in a roll, makes formed stools easier to deal with. It can simplify changes at nursery, on trips or when someone else is caring for your baby. Very runny stools can pass through or cause the sheet to bunch up. Put the used liner in the bin, even if it is labelled biodegradable.
Which liner suits your routine?
For runny stools or a baby who dislikes dampness, try washable fleece. Once stools are formed, either option can work. You might prefer fleece at home and overnight, and disposable liners at nursery or while travelling. For a low-waste routine, plan roughly one washable liner per change between washes, plus a small reserve.
How to use a liner
Put the insert or absorbent layer in place first. Lay the liner on top, next to the skin, and tuck all edges inside the nappy elastics to prevent moisture wicking out. Empty stools into the toilet, then wash the fleece liner or bin the disposable sheet. Follow the care label and avoid fabric softener. This placement works with pocket nappies, all-in-ones and two-part systems.

Frequently asked questions
Do I need a liner?
No. A cloth nappy works without one. A liner makes stool clean-up easier, and fleece can feel drier against the skin.
Can I flush disposable liners?
No. Empty stools into the toilet and put the liner in the bin. Biodegradable does not mean flushable.
Can fleece replace an insert?
No. The insert provides absorbency. The thin fleece liner sits above it.
How many washable liners do I need?
Allow roughly one per change between washes, with a few extras.
Can I wash an unused-looking disposable liner?
Some products tolerate an occasional wash if they have no stools on them. Follow the manufacturer's instructions and discard damaged or misshapen liners.
Which liner works from birth?
Washable fleece often stays in place better with the runny stools common in the first months.
