Are glass bottles unsafe for breast milk?

I'm due in a few months and I have read that some plastic bottles can allow oestrogen-like compounds to leach into the milk. I am interested in using glass bottles and will be breastfeeding but have read that glass bottles are not recommended for breast milk. Why would this be?

You were given some incorrect information about glass bottles. There is no problem using glass bottles with breast milk or formula. The only disadvantage is the possibility of glass breaking. Brown glass is reportedly the best to use as light does not pass through as readily and cause any breakdown of milk, but clear glass is fine to use as well. You've made a great choice to breastfeed. Good luck!
