Great suggestions everyone. I'm really not that sensitive, but this really tasted like plastic. Think I need to get a Polar. I've never liked the nipple bottles, so I hope Polar has the flip caps. (tsl: Goose poop?)
I had a friend who had such a sensitive palate that if anyone brought coffee for her from the local SB, she could tell if they had used a wooden or plastic swizzle stick to stir in the sugar! She hated the taste of wood in this case.
