For those of you freaked out by the reports of BPA in bottles, I found a site that helps you figure out which are "safe". Z Recommends gives you a list of the brands to avoid, that aren't recommended, are safe, and are promising entrants. Check it out! It tells you which of each brand is BPA free and which aren't.
As a result, I'm getting rid of the breastflow and now feel better about the NUK pacifier.
