I use Avent now, but when my baby was a newborn he didn`t take to it. I don`t know if it was the wide nipple area or what. I ended up getting the glass Pigeon bottle, but by then he refused all bottles until 8 months later when he preferred the Avent one. Go figure. The BPA ones are expensive here, over $100 each. If you`re planning to buy a pump, I think they come with some bottles(my Avent did) so you can just go from there.
