We've got one controversial word for you: plastics. After a panel of specialists in environmental health said they had "some concern" that infants exposed to bisphenol A (BPA) could experience neurological and behavioral problems later in life, many moms tossed their supply of baby bottles and sippy cups made of the clear, hard plastic that commonly contains the chemical. Wondering whether you should follow suit? Many experts say there's no need. The U.S. Food and Drug Administration is actively reviewing BPA and states that the current exposure levels in baby bottles and sippy cups do not indicate a safety concern. If, however, you want to err on the side of the extremely cautious, here's how:

* Go for (usually BPA-free) colored or opaque plastic bottles and cups.

* Buy bottle systems with soft, disposable plastic liners.

* Check the triangle on the bottom: Number 7 usually indicates BPA.

* A company called BornFree makes BPA-free plastic bottles, but they are pricey -- about $10 each.
