Kristen asked, “Will you please explain the BPA concern in bottles? There is quite a bit of information about it, but I’m having a hard time determining if the bottles I use contain it or not since I don’t see any number on my bottles (Avent). Is a drop in system the best alternative while companies are determining which products are safe? Thanks for any information and help in finding the ‘correct’ bottle.”
As with many issues of toxins and exposures, no one knows with 100% certainty that the amount of BPA that a bottle-fed baby is exposed to will definitely never cause any health problems. I will say based on the available data and the best studies, BPA is almost certainly not something that’s going to harm your child. There are BPA-free alternatives if this is something that you find yourself continuing to worry about.
