Can someone link me to a website that describes the safer plastics vs. more dangerous?
I have an Avent Isis breastpump and I have been using the converter with the Via cups since they are #5 and the regular Avent bottles are #7.
#5 is safer than #7, right?
(for the record, after pumping I then transfer the milk to glass for freezing).
I know that #7 is one of the worst, but forget what the other numbers mean.
Links, please!
