BPA and babies: Feds acknowledge concerns
Federal health and research officials outlined new guidance today for parents on the use of plastics made from bisphenol-A, a hard, clear plastic. Their bottom line: Minimize BPA-based products that could make contact with foods or drinks that infants or toddlers might consume — especially hot foods and drinks.

Nor did it call for parents to avoid processed infant formulas and baby foods — some of which it acknowledges are contaminated with traces of BPA.
