They is so much hype about it out there right now. I am still using my Avent bottles...I did just see this on Nightline the other day, they tested how much BPA is in bottles etc, and the highest amount was in plastic water bottles (including the 5 gallon arrowhead ones) and the 2nd highest was in the cans of "things" (green beans, corn, beans, tomatoes sauce etc) I can't remember off hand what the other ones were, but baby bottles were number 4 on the list. I didn't want to spend the money buying new bottles, when 6 mos. from now they will tell me somthing is in the other ones that is just as bad. So much stuff out there. For me, they say bleach, dish soap and windex have all been proved to cause cancer. I like my whites white, and my dishes clean, and my windows streak free. They tested a completely "green family" in comparrison to a not green family, and the green family had just as many chemicals inside of them as the not green family on the same show. It was scary, I thought forsure the green family would be so much better. Good luck in your decision!
