Cloth nappies for heavy wetters: how to prevent leaks

Is the nappy soaked through or leaking while the insert is still partly dry? That difference tells you where to start.

Check the cause before adding bulk

A fully soaked insert suggests the nappy has reached its capacity. If the insert is mostly dry, check its position, the leg seals and whether water beads on the fabric. Tuck the insert and liner inside the waterproof shell. If leaks happen in a car seat or carrier, pressure on a saturated insert may be squeezing moisture out.

Choose a booster for daytime or night

Start with one booster if your usual daytime setup fits well. For a longer nap or overnight, try a fast-absorbing cotton layer above a higher-capacity bamboo insert. A dedicated overnight nappy can give you more capacity without stacking so many layers that the leg seals gape. Keep microfibre away from direct skin contact.

Test one change at a time

Check the fit at the legs, note where the leak starts and see how wet the insert is at the next change. Try the same setup two or three times under similar conditions. If the insert has a persistent smell or repels water, review the wash routine before adding more boosters. Keep up regular daytime changes.

Do two inserts always solve the problem?

The materials, fit and time between changes all matter. If the extra layer creates gaps around the legs, try a higher-capacity insert with less bulk.
