After every session
Rinse milk-contact parts promptly. Wash with mild soap and warm water, then air-dry on a clean surface.
When to sterilise
Follow paediatric guidance for your baby's age and health. Many families sterilise daily in the early months, then reduce frequency as advised by their clinician.
What not to do
Avoid harsh scrubbing on silicone flanges and do not put non-washable electronic parts in water.
