The safest choice is clear: Breastfeed your baby whenever possible

I ran into this article taken from the Environmental Working Group (EWG) website on the latest research on toxic chemicals found in the lining of formula packaging. Read more details here.

Liquid infant formula from the top manufacturers is sold in cans lined with a toxic chemical linked to reproductive disorders and neurobehavioral problems in laboratory animals, according to an investigation by Environmental Working Group (EWG). The chemical is almost as common in the packaging of powdered formula, with 4 of the top 5 companies acknowledging its use.
The chemical is bisphenol A, or BPA, a component of the plastic epoxy resins used to line metal food cans. Dozens of laboratory studies show that BPA affects the developing brain and reproductive systems of animals exposed to low doses during pregnancy and early life.

For a healthier choice, Breastfeed whenever possible. Breast milk is the best source of nutrition for babies. It contains essential fatty acids that help bolster babies’ bodies against the impacts of toxic chemicals. However, there are many reasons why families rely on formula for some or all of their baby’s diet. Seventy percent of babies in the U.S. receive some formula by the time they are 3 months old. These babies need a safe and healthy source of food, and formula should be manufactured in a way that avoids contamination with harmful chemicals. Research breastmilk and why it's best for your baby and you will soon agree that it is the best choice for your baby.
