I am using Avent bottles (not BPA free) with my 4 month old but want to switch. I have been researching Bornfree and Dr. Brown bottles but am concerned about all the extra parts involved.
Also, what should I do with the Avent bottles, some of which have never been used.

Honestly, I never really cared about this topic…how many babies have used these bottles and are fine?? MILLIONS!!
There are more important things to worry about…

I am under the impression that BPA is only transferred to formula when heated, so I bought a BPA free bottle and have been using it to heat my baby’s formula up in and then taking his favorite Dr. Brown bottles and putting it in there. We have invested in 16 Dr. Brown bottles and I don’t have the $$$ for a lot of BPA free bottles. Am I safe heating the formula in the BPA free bottle and then transferring to the Dr. Brown ones? Anyone else using this technique?
