I am having sort of a dilemma deciding what to do about my breast pump situation. I am currently 32 weeks expecting twins the end of february. I am definitely planning to breastfeed but will have to go back to work after 8 weeks. My first dilemma is that my sister in law has offered to let me use her medela pump in style advanced which I know is a really good offer, but it's not only been used by her but also a friend of hers. As I have researched the sharing of certain breast pumps and consulted with a lacatation specialist I have learned that this is not recommended due to contamination and risk of possible infection to my newborns. Her argument is that if something were wrong with it her baby would be sick and he's not. My second dilemma is that my job is very demanding--I work 12 hour shifts with essentially no breaks and I will need to be able to pump as quickly and as efficiently possible. I am considering the speed and efficiency, portability, etc. of this breast pump versus the medela freestyle. The freestyle is much lighter and I believe easier to lug back and forth to work everyday without everyone knowing what it's for. I know the price of a new breast pump is much cheaper that paying for formula for a whole year especially for 2 babies but I am having a hard time turning down a free breast pump. I'm not sure what to do. Also, if I decide to buy the freestyle I have a 20% off coupon that I can use at babies r us later this month. I know this probably sounds trivial to you guys but I really need some help deciding what is best for my babies and my work situation. Thanks for your help.
