Connecticut's attorney general says six companies have agreed to stop manufacturing baby bottles that contain Bisphenol-A, a chemical some studies suggest may be harmful to infants.
Attorneys general from Connecticut, Delaware and New Jersey sent letters last October to 11 companies, asking them to stop using the chemical.
Connecticut Attorney General Richard Blumenthal says Avent, Disney First Years, Gerber, Dr. Brown, Playtex and Evenflow have agreed to the request.
Blumenthal says the companies stopped manufacturing bottles with BPA a couple of weeks ago.
On Wednesday, lawmakers in Suffolk County, N.Y., became the first in the nation to vote on a ban on baby bottles and toddler sippy cups made with BPA.
