BPA can get leeched out of the bottles and into the milk. This
happens especially at higher temperatures or when the bottle or cup
is getting older, says Anjali Rao, a pediatrician with Northwestern
Memorial Physician's Group.
We love Sigg's water
bottles for their fantastic kid-friendly designs added to their
BPA-free, phthalate-free, VOC-free interior. And we adore the Klean Kanteen line of
stainless steel baby bottles, sippy cups and water bottles. They're
also free of BPA, lead, phthalates and toxins.
