There is lots of debate regarding microwaving plastics, even if they are BPA-free.

Curious if there is a definitive risk of using a microwave sterilizer (steriliser) (such as the Avent) vs. using an electric steam sterilizer (also made by Avent) with BPA-free bottles.

This may be more suited for . Anyway microwaves only heat the water so the risk is the same in both cases imho. – w00t Sep 24 '12 at 20:38
What is the concern about microwaving plastics, when it's not BPA? – Torben Gundtofte-Bruun Sep 28 '12 at 14:08

I don't think there's enough research in the matter to make a judgement, studies on these types of things take years, and often contradict each other. I'd be on the safe side and use an electric steam sterilizer as I don't know the answer. there's other good reasons for using an electric one:

  • They are nearly silent, and microwaves are noisy
  • They are a bit more efficient than microwaves. Microwaves are an expensive way to boil water, which is all that sterilization is about really

the issue with bottles containing BPA is not the method of heating, it is the fact that any heating results in the leaching of Bisphenol-A into the baby's milk.

Using a BPA-free bottle means that any form of heating is safe (as long as the temperature is tested thoroughly!). Check out for a wide range of BPA-free bottles and PVC-free toys.
