A group of experts concluded that bisphenol A may have some effect on the behavior, brain, and prostate gland of a developing baby (fetus) or young child.1 If you are concerned about BPA, don't use bottles marked with the number 7 or the letters "PC" near the recycle symbol. You can use glass or BPA-free plastic bottles instead. For more information about BPA, see the website www.hhs.gov/safety/bpa.
