I am only breast feeding my baby, when I use the breast pump do I have to sterilize it after each time or just wash it with soap and water? Knowing that I pump my milk 7 times a day in order to decrease the flow from my nipple to help the baby eat without

Breast pump. It is alright to just wash theglass portion with warm soap and water after each use and drop it in the dishwasher once a day.
Simple cleaning. Handel this as you would your dishes and eating utensils. There is no need to sterilize everything.Regular soapy water cleansing atter use of any involved surface in contact with the milk is fine.
