With the new information that even BPA-free alternatives aren't safe for our little ones, more and more moms are turning to glass bottles. We particularly love the Joovy Boob version for it's revolutionary new nipple design, where they are molded instead of cut for the perfect flow (speaking of which, there are 5 flow options from preemie on) making it a seamless transition for Baby from breast to bottle and back. The nipples are also baked which helps prevent the dreaded nipple collapse that seasoned parents are well aware of. If you're worried about the breakability of glass, you can purchase a silicone sleeve to protect the bottle.
