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. It gets top reviews from expert reviewers, and the overwhelmingly positive feedback from parents suggests that this colic-prevention feature is indeed an improvement over standard baby bottles.
Dr. Brown's bottles went entirely BPA-free in 2008, and now contain no BPA, PVC or other harmful plastics. Be sure you order only bottles manufactured after 2008. These bottles have more parts than most, but none small enough to present a choking hazard.
Dr. Brown's anti-colic system relies upon an assembly that includes a nipple with ring, vent system and straw, in addition to the bottle. While it's this system that controls air in the liquid, it can be difficult to assemble, disassemble and clean. The parts also have to come together just right for the bottle to work correctly, which can be difficult to manage with one hand while holding a baby. Once the bottle is assembled, reviewers say it is easy to use. They also say it gets easier with practice.
Once taken apart, the bottles are easy to clean and dishwasher safe on the top rack. There are a few reports of leaking, but not many. They come in both standard and wide-neck designs. There's not much difference between the two, except the wide-neck design makes the bottle easier to clean.
Because of the anti-venting system, formula is more difficult to mix well in this bottle. Pre-mixing in a separate container may result in a more thorough mix.
Dr. Brown's bottles are popular for a reason, in spite of their less-than-user-friendly assembly: The anti-colic system really does work, according to most parent reviewers. A few even say their children born with rare feeding issues can only be fed with Dr. Brown's bottles. Two expert review sites selected Dr. Brown's as the best bottle for preemies with the optional Preemie Flow nipple (*Est. $4 for a pack of two).
Some parents complain that Dr. Brown's bottles are expensive, but they actually fall somewhere in the middle of the price point when compared to other bottles in this review. The wide-neck bottles are slightly pricier, but there is no real difference between the two bottles other than the neck.
Dr. Brown's is our pick for a colicky baby. You can't argue with success, and Dr. Brown's bottles earn high praise for colic prevention. Yes, they can be a pain to assemble; If done incorrectly, it can lead to leaking, a fussy baby and a few frantic moments. But if your baby suffers from gas, this bottle is the one most apt to fix the problem.
In more than 1,000 reviews, Dr. Brown's bottles earn a score of 86 out of 100, primarily because of their anti-colic feature.
