Now I'm not usually one to talk about the dangers of chemicals and toxic substances, but we've recently found out that there may be some concerns about some of the plastics that we use. The chemical is called Bisphenol A (BPA) and it is present in all polycarbonate plastics. After reading the "Smart Plastics Guide Healthier Food Uses of Plastics" issued by the Institute for Agriculture and Trade Polcy - Food and Health program (and doing some other internet research); Roger and Tracey have now decided to switch all of Malcolm's baby bottles from the current Avent system to the Gerber Gentle Flow bottles. The Avent bottles are made of polycarbonate and although they have been very good, a change is now due. Here's a picture of the Gerber bottles below. Oh, incidently they are alot cheaper than the avent bottles and are stikingly similar; so similar in fact that we are able to use the collars and nipples interchangeablely. We got ours at Walmart.
Some companies have even gone as far as marketing their bottles as BPA free (Evenflow and Born Free). Now most of the studies report that there is no danger to humans, or that the levels are well within the allowable limits for human consumption. Sure, although that may be well and true, why would you knowingly subject yourself (or our son for that matter) to something known to be harmful. Malcolm will not be drinking from polycarbonate plastic anymore.
