But, on further reading, not only are the study results highly inconclusive (only found in one study, no ability to reproduce it yet), and not only is there no clear correlation between the effect on mice and the effect on humans, but the leaching of BFA only occurs when you heat the bottles. Definitely some leaching occurs at high temperatures; it's unclear whether it occurs at lower temperatures. Since we essentially never heat the bottles for Kavi, I have now heaved a sigh of relief. We did heat them a few times initially, but quickly realized that there was no need -- she's perfectly happy with room temperature milk, and will even drink refrigerator-cold milk. We usually take it out of the fridge and let it come to room temp if we remember, but she doesn't really care if we don't. There's a parenting tip for you -- if you don't train your baby to expect warm milk, she'll probably happily adapt to cold. :-)
Anyway -- here's the best article I've found so far on BFA leaching in baby bottles, if you want more details.
