Dr. Brown's Natural Flow

Dr. Brown's Natural Flow baby bottles have an unusual design that incorporates a straw-like tube vent to help prevent babies from swallowing air when they drink. The overwhelmingly positive feedback from parents suggests that this colic-prevention feature is indeed an improvement over standard baby bottles. This bottle's standout feature does have a downside: parents say it's cumbersome to put together and tricky to clean. If your baby doesn't have trouble with gas, a simple inexpensive bottle like the Evenflo Classic Glass Nurser (*Est. $2 for one 8-oz. bottle) might work just as well. It's also possible to get a bottle with a simple anticolic vent instead. BornFree Bisphenol-A Free (*est. $18 for two 9-oz. bottles) are also said to be effective at reducing gas and colic, and they're much simpler to clean. MAM's Anti-Colic bottle (*Est. $13 for three 8-oz. bottles) also gets good reviews, although it also requires some finicky cleaning and assembly. Dr. Brown's Natural Flow does come in a good selection of shapes and sizes, and is now BPA-free.
