Product Description

Size: 8 Ounce

Dr. Brown's bottle features a patented two-piece internal vent system that works unlike any other bottle design. The vent system fully vents our bottle for vacuum free feeding, which we call positive-pressure flow, similar to breastfeeding. As the baby feeds, air is channeled from the nipple collar through the vent system, bypassing the breast milk or formula, to the back of the bottle. Air never mixes with the breast milk or formula which minimizes oxidation and helps maintain essential nutrients like vitamins C, A and E. Babies feed more comfortably because the vent system allows them to nurse without fighting the negative effects of a vacuum or the discomfort of ingesting air bubbles. This helps to reduce feeding problems like colic, spit-up, burping, and gas. The breast milk or formula flows freely, without nipple collapse. Includes two 8 ounce glass bottles with two level one nipples, two 2 piece internal vents and one nipple cleaning brush. BPA Free.

Over all we would recommend this product in a heart beat, after using these for 9 months, this is the pros and cons list we've come up with so far. Our daughter has always been prone to gas easy for multiple reasons, this was the only bottle that aided in the prevention of gas and colic the best. We noticed a difference immediately.

To help with cleaning we suggest keeping all the pieces soaking in some soapy water after each use until it's time to clean all the bottles (unless you clean after each use), it helps keep the pieces looking clean and new, it helps with the mildew issue. (Below in the cons list it explains more.) Dawn Ultra seems to work the best so far or the Dawn Power Soaks.


1--> The brown inserts that go into the blue straw/tubes collect mold and mildew fairly easy and need to be scrubbed and soaked every day. These pieces will color over time and get nasty looking. After around 7 months they need to be replaced , that is when our bottles began leaking. We replaced these pieces recently and the problem stopped.

2--> The tiny brush that comes with the bottles does not clean the brown inserts well, they are only good for the little holes and the nipples . We suggest investing in a good nipple brush so you can get all the gunk off successfully .It also gets lost easy due to it being so tiny and a clear'ish color. The Munchkin Deluxe nipple brush has worked best so far.

3--> Cleaning all the parts and pieces is a huge chore every day but it 100% worth it. Also, because of this reason, we would not recommend this bottle for parents of multiples or multiple children unless you have good help. Or unless your child really,really needs the extra help this bottle offers.

I love these glass bottles! The pictures are not accurate to what the bottles look like though, which for once is a good thing! These bottles don't have any labels on them, the Dr.Brown's is actually etched on the bottle as are the oz's, which means no pealing or flaking. The bottles are a little heavier than the BPA free ones obviously because they are glass. My daughter threw one on the floor many a times the days following purchase and not a crack or chip! These bottles are also 8 oz I'm not sure why it took so long to come out with the 4 and 8 oz versions, but I have both and love them! They clean easily enough and can go right in the dishwasher and come out spotless! I am very pleased with Dr Brown's bottles and their customer service! If you've ever had an issue and had to deal with a customer service rep from Dr Brown's they are EXCELLENT! They fully stand behind their product!

I bought these out of concern for BPA. We also had the regular plastic Dr. Browns. A few differences to point out. Oh, and my husband used these with pumped breastmilk (I don't know if that makes a difference).

1. These warm faster than a plastic bottle, so we tended to prefer these over the plastic

2. Obviously, plastic is not going to break - so if you have concrete or tile (where you're feeding) you may want to skip these. One of ours bit the dust on the kitchen tile. We dropped them a few times on carpet with no issue.

3. I felt like these were easier to clean than the plastic. It was easier to see the "dirt" in the bottom than with the plastics.

We previously purchased the 7oz Dr. Brawn Glass bottles. When we went to the store to get more they only had the new 8oz glass bottles. We got a pack of 2. A couple days later the day care told us that one of the bottles broke while warming it in the bottle warmer. We first thought that they may have done something wrong, however the next day, a bottle broke for us at home while warming it up in the Dr. Brawn bottle warmer. It broke at exactly the same place as the one at the day care - the bottom of the bottle got detached. It looks like someone just cut it off.

We called the company and they tried to tell us that the bottles can break when changing extreme temperatures. The bottle at home was not cold and the milk was not too cold when we put it in the Dr.Brawn bottle warmer. Changing temperature is definitely not the reason for breaking those bottles. We also wanted to make sure the company is aware of the problem with their bottles. They said that they have not received any complains about this issue (which is very interesting, especially after reading some of the reviews above reporting that the bottles break). The company sent us 2 new glass bottles and a sleeve. We tried putting the bottle with the sleeve in their brand bottle warmer but it didn't fit, so we warmed it without it. Two days later one of the bottles they sent us broke-again at the exact same spot. We have save all 3 of the broken once and they look exactly the same. At this point we are convinced that there is something really wrong with the design of the 8oz Glass Dr. Brawn bottles and the company doesn't want to admit it and fix it. The 7oz glass bottles that they discontinued and that we are still using are working great. Their glass looks a lot better quality as well. If you still want to buy the new 8oz once, be aware that you may lose a lot of milk or formula because they keep breaking.(See the additional pictures of the product)
