I am planning on breast feeding but will definitely need bottles because I have to go back to work. I'm a stepmom and hubby doesn't really know what he thinks works best as kiddo was almost exclusively breast fed by his mother. I wanted to do glass as I think glass is generally safer, but since I'm going to have to freeze breast milk I think I have to use the breastmilk bags anyway... I am so confused as to what to buy. a coworker told me the lansinoh milk bags were the best as far as being sturdy and not breaking open over other brands, and I see they are labeled bpa free... do they make bottles that fit those bags? is it a pain to use that brand with a medela pump (what i have) or any other opinions on what is the best? I'm so overwhelmed with choices... 36+6......
