i'm hoping that they come up with a bpa-free version before i give birth in august. riight... i guess i'll have to get another type of bottle. i'm thinking of glass bottles. i might steer clear of the plastic bottles because you never know what they'll discover a few years from now. 5 years ago, avent was the best bottle around and now, they're found to have bpa! you can check if your bottles are bpa-free at these websites:

they also rate and recommend bottles. good luck to all the mommies and daddies out there who are stressing out about bpa!
