FAQ

Why does breastfed poop blow out so often?

Breastfed stool is runny / seedy and travels up the back when babies are flat on their back. Cuddle Kin's tall back panel contains it.

Should I size up?

If blowouts persist at the top of the size band, size up β€” gives more back panel coverage.

What if it still leaks?

Try changing within 5 minutes of a feed when poop frequency is highest 0-3 months.

How fast can a Cuddle Kin handle a blowout-clean-up?

Bamboo is gentler on baby's skin during multi-wipe cleanup vs synthetic.

OEKO-TEX certified?

Yes β€” OEKO-TEX 100 Class I.
