How (often) Should I sterilize my Lansinoh manual breast pump?


Hi! I have a 6-day-old baby boy and have a lansinoh manual breast pump. Friends told me I only need to sterilize my pump every three months by putting it in boiling water for only a minute, while some others told me I should boil it every time I use it. I searched online and could only find very contradictory suggestions. Please kindly let me know what I should do - how often I should sterilize it and how? Many thanks!



We recommend that you sterilize your breast pump before your first use, by boiling the parts for 5-10 minutes and then allowing them to air-dry. After the first sterilization it’s at your discretion based on how often you use the pump and if you are cleaning it immediately after each use. To clean after each use soak the parts in warm soapy water and then rinse and allow to air-dry. If you do choose to sterilize follow the same instructions as before.

Kindest Regards,
