Polycarbonate plastic is a popular choice for manufacturing baby bottles, because it is shatter-resistant. However, the BPA found in polycarbonate baby bottles worries some scientists. The average onset of puberty in girls has been decreasing in age over recent years, and some scientists believe BPA is partly to blame. BPA acts as an endocrine disruptor, which means it may contribute to early puberty and changes in breast tissue, the prostate gland and sperm production in offspring. To protect infants, the states of Minnesota and Connecticut, the city of Chicago, and Suffolk County in New York recently banned the sale of baby bottles and sippy cups made with BPA. Canada’s government has proposed restrictions on BPA and banning polycarbonate baby bottles. Major manufacturers and retailers have also announced voluntary bans.
