I am an expecting mother (due ~ end of May), and have been overwhelmed with the amount of choices with bottles. I hope to be able to breast feed, and have recently purchased a Medela Pump In Style Advanced shoulderbag pump. Are there any BPA-free bottles that are compatible with the Medela (can pump directly into the bottles)? In particular, I'm looking for something that is vented to reduce the chance of colic.
Also, if I get a non-vented bottle, will "vented" nipples work?
