I use glass bottles: lifefactory and bornfree. I really love them both! Also, if you plan to bf and pump, you can buy the little glass, I think, evenflow bottles to use with your pump. They are very inexpensive and sold in like a 3 pk at target.
I was given a large collection of glass bottles, big and small. But I was warned when I got them that I would eventually need plastic when the baby holds and throws them. I hope to not need them, but would just go for BPA free. I am concerned about chemicals leaching out of plastics, but I just plan to minimize LOs overall exposure.
