I've been researching this a little myself, and here's what I've found. This website (
http://zrecs.blogspot.com/2007/07/z-...carbonate.html) lists several manufacturers and tells you which bottles are BPA-free and which are not. It's a very helpful resource, though still a little incomplete. If you're wanting traditional plastic bottles, I can tell you that a lot of manufacturers are slowly jumping on the BPA-free bandwagon. For example, Dr. Brown's came out with a glass bottle last month, and they will be coming out with a BPA-free plastic bottle in late March 2008. This is great if you need a bottle that reduces air. Of course, the other option is to use disposable bottle liners. Most, if not all, are BPA-free, and they also reduce the air that your baby ingests (without the contraptions you find in bottles like Dr. Brown's). And, yes, they do make bottle liners that also store your breastmilk. The Avent Via system uses BPA-free
bottles that allows you to pump your milk directly into the bottle, store in the bottle, and feed directly from the bottle. The catch? It only works with the Avent ISIS breast pump. Playtex OneStep is another pump-store-feed system that is BPA-free, uses liners, and works with MOST pumps (except the Avent and First Years pumps). I am planning on using the Amedia Purely Yours (since it's cheaper than the Medela, lightweight, and highly recommended by Baby Bargains), but I am not sure if it's compatible with the Playtex OneStep. There are other freezable bottle liners out there too, like the Gerber Seal-n-Go liners, but this is not a pump-store-feed system (though perhaps they can be used with the other kits??). I do know that the Medela Pump In Style comes with storage bottles that are BPA-free, while the storage bottles that come with the Ameda are not BPA-free. Anyway, this is a lot of info, but I hope it's helpful! I have spent way too much time on this already, so if I can save someone else time, then GREAT!
