When it comes to sterilizing your breast pump parts, there are a few important steps to follow. Start by thoroughly cleaning the parts with warm, soapy water. Rinse them well, then place them in a pot of boiling water for 5 minutes. Alternatively, you can use a steam sterilizer or microwave sterilizing bags. Remember to always wash your hands before handling the parts and store them in a clean and dry place. Regularly sterilizing your breast pump parts is crucial to prevent the growth of bacteria and ensure the safety of your baby's milk.
