No- no mix-up in the article- it is true that #7 is bad- this is what the article says:
polycarbonate bottles are made with bisphenol-A (BPA), a chemical that when leached in sufficient quantties, has been shown to alter hormone function and chromosome alignment in mice and their reproductive cells (Current Biology, 2003, vol. 13) however the human health effects of this plastic have not been established. in fact, other studies, some funded by the plastics industry, have not found any health risks associated with BPA exposure.
that's what it says and lists it under the heading: USE THESE PLASTICS WITH CAUTION and lists #3, 6 and 7.
I know Nalgene bottles are made of this too. Now I reuse glass juice jars for carrying water. What about those BIG jars of Santa Cruz apple juice for water storage?
i will try just a cup with my little one and ditch the new #2 sippy. the suggestion about small sips in small cups has been very helpful. i think we can do this!!! thx for the inspiration

that's why i love these boards- you not only don't think i'm nuts but you can relate and help out !!! thx......
