I was wondering if anyone has used the Medela Freestyle pump? Did you like it? Could you actually move around the house easily while pumping? I used the Medela in Style for my first baby and it worked great love it, but I like the idea of the freestyle for baby 2 since I will have a 2 year old while I'm trying to pump. The in style you are tied to an outlet and can't get up fast if needed. Any opinions?
