Bisphenol A Free Sippy Cups or BPA Free Baby Products

Here are links to two opposing articles you can read on Bisphenol A. 

The use of polycarbonate plastic for food contact applications continues to be recognized as safe by the U.S. Food and Drug Administration, the European Commission Scientific Committee on Food, the United Kingdom Food Standards Agency, the Japan Ministry for Health and Welfare and other regulatory authorities worldwide." You can find more information on this at:

Just a note on any plastics and heating baby items:

If you don't put hot or warm liquids in your sippy cups, the chances of the BPA chemical being released is much less likely than if you put hot drinks in your baby's sippy cups.

The same goes for heating any foods in any type of plastics in the microwave.  The chemicals will leach into the foods and those chemicals, according to many articles you can find on google, are much more harmful than Bisphenol A.

The Bisphenol A Free Sippy Cups and other bisphenol A free baby products controversy continues.

Some studies have concluded that Bisphenol A is harmful to your child, while others are stating that the amount of bisphenol A that you would have to consume to be harmful would not even be possible during your lifetime.

Regardless of the controversy, for those who like to err on the side of safety, just in case, many of the Nuby sippy cups either always have been or will be BPA (bisphenol A Free) in the near future in response to the concern.

The Nuby Sippy Cup Replacement Spouts are BPA (bisphenol A free) and you can order those from my ebay store at:
