Please advise!!! I bought an electric Medula(sp) from ebay second hand two days ago. I then saw on net it says do not use secondhand pumps as you can contract all sorts of diseases even if they have been sterilised. Obviously the motor is not sterlised rest is, website says bugs can sit in the non sterlised parts. Should I stop using it, is it dangerous? Total panic have harmed 6 week DD.
