Dr. Brown's Natural Flow Glass Review
Price: $6.67 List
Pros: Glass, silicone sleeve, price
Cons: Nipple, complicated, heavy
Bottom line: Glass w/complicated valve system that is hard to clean/assemble.
The Dr. Brown's Natural Flow Glass Bottles are easier for baby to use than mom and dad (not counting the heavier weight). This bottle has many parts and pieces that make cleaning and assembly difficult and only possible with the special bottle cleaning brush included with the bottle. While it has an interesting vent system that makes some unique claims and it is often recommended from one parent to another, we weren't as fond of this option as we were the Lifefactory glass bottle that performed better in our tests and won our Editors' Choice award.

Analysis and Hands-on Test Findings
Dr. Brown's Natural Flow Glass Bottles offer the benefits of glass and their vent system. It uses the same silicone nipples as their standard bottles and is BPA, PVC, lead and phthalate free. The design creates a vacuum free feeding more akin to breastfeeding to help reduce colic, spit up, burping and gas. This bottle is made in the USA. Dr Brown's bottles use a patented 2-piece internal vent system that creates positive-pressure flow for that is similar to breastfeeding without nipple collapse. Air is funneled from the nipple collar to the back of the bottle through the vent system. It doesn't mix with the milk to help maintain essential vitamins such as C, A, and E. Each bottle includes 1 cleaning brush and instructions.
Munchkin Latch scored as well in our tests for leakage.
Philips AVENT Natural Glass, and unlike the one found on the Lifefactory bottle it is easy to remove and clean. This sleeve can make the glass heavy bottle easier for baby to hold and help prevent accidents should it be accidentally dropped.
Other Versions and Accessories
Dr. Brown's does offer some accessories that work with their bottles well and might be worth a look see if you decide that this is the best bottle for your baby. To warm bottles to feeding temperature, Dr. Brown's Deluxe Bottle Warmer tied for third place in our best bottle warmer review. It might also be a good idea to have back up glass bottle sleeves in case your becomes damaged or lost. Last, you might want to consider standard travel caps that allow you to use the bottles for storage or travel without the nipple and vent system in place.
