Title: polycarbonate plastic a concern
Review: ...These would be great except they are made with polycarbonate plastic which can leach a potentially harmful chemical called bisphenol-A. The problem worsens the older and more worn the plastic becomes. I would be concerned if I were to sterilize these containers frequently or if I sterilized formula while in the container (but most people don't do that anymore...
