Piggybacking T.T.'s response, if you nurse, you'll want to get a bottle with a deep nipple (with a baby bottle, babies just mash the nipple whereas with your breast, they pull the nipple all the way to the back of the throat so your nipple doesn't hit the hard palate - hence the recommendation to avoid bottle feeding until you have established a proper latch and good milk supply, around 6-7 weeks). Anyway, my lactation consultant recommended Dr. Brown's - they are BPA free. Never had any issues with it and both my children took it well and we were able to continue breastfeeding, even after I went to work. Good luck!
