I got a breast pump through my insurance that a friend of mine told me is incredibly slow and weak compared to some models out there. I had my breasts augmented about 4 years ago and have one breast that I really struggle with when pumping--it will produce only about a forth of what my other breast will while pumping. Anyone have recommendations for a great pump? I'm not too concerned about the cost...just want something that can get the most milk out for my baby girl.
