You would think in all the things that can have a dangerous chemical baby bottles are safe because they are intended for use of very fragile human beings. It's a shame that we, humans have produced things that are harmful for environment and us. Unfortunately we went too far and I hope that all these talks about being green and living green make some changes, otherwise I'm too scared of the future of our children to dare think about it.

I try to stay away from plastic bottles. Glass bottles can be used effectively under supervision however I would recommend using silicone bottles.
