BPA-free great. But if the replacement is BPS (bisphenol-S) or any other bisphenol WATCH OUT!
Not only does BPS appear to have similar hormone-mimicking
characteristics to BPA, but research suggests it is actually
significantly less biodegradable than BPA, which means that it may be stored in the body and persist in the environment longer.
So dump the BPA-free sippy cups & baby bottles, glass is best.
try these glass baby bottles, but stay clear of the 'bpa-free' sippy cups on the site.
