Wash your breast pump kit in a wash basin – CDC
Providing breast milk is one of the best things you can do for your baby’s health and development. Pumping your milk is one way to provide breast milk to your baby. However, keeping the parts of your pump clean is critical, because germs can grow quickly in breast milk or breast milk residue that remains on pump parts. Following these steps can help prevent contamination and protect your baby from infection. If your baby was born prematurely or has other health concerns, your baby’s health care providers may have more recommendations for pumping breast milk safely.
Clean pump parts that come into contact with breast/breast milk as soon as possible after pumping. You can clean your pump parts in a dishwasher or by hand in a wash basin used only for cleaning the pump kit and infant feeding items.
