I'm constantly being asked by new clients what bottles they should get, and quite honestly I like the old school ones like these as first bottles, until we figure out what kind of eaters we are working with. They are affordable, easy to clean, all are BPA free now, and right size nipple for tiny mouths. Very similar to the nipple that fits on the hospital nursettes, in shape and size. Some babies show a definite preference for either silicone (clear), or latex (brown) ones too. Even then, I am not a fan of any of the other fancy, 5 part bottles. If you like them, get them, but remember a lot of baby stuff out there is just a gimmick!!
