Dr. Brown's bottles features the Patented Internal Vent System which eliminates the negative pressure and excess air ingestion. This system is the only vent that eliminates the vacuum and the air bubbles found in most baby bottles. It allows air to enter through the nipple collar without being incorporated into the breastmilk or formula.

Dr. Brown's vs. VentAire vs. Breastflow Feb 13, 2011
By sdteacher In the first month and a half of my baby's life, we went through an enormous challenge trying to breastfeed, but, due to low milk supply (yes, I tried Fenugreek and a bunch of other stuff!), switched to mostly formula. We experimented with a bunch of bottles, so here is a comparison review:
Least Favorite: The First Years Breastflow The First Years Breastflow BPA Free Bottle 3-Pack, 5 Oz
We tried the Breastflow first because it was recommended by my lactation specialist as being the closest to the breast. In that respect, it does have an advantage. I haven't seen any other bottles on the market designed to mimic the mother's nipple the way these are. However, there were other problems with this bottle that ultimately made it my least favorite. Primarily, the flow was extremely variable. At times we would find it was flowing so fast my daughter would be dribbling everywhere, and then at the next feeding it would be so slow she could barely get anything out. This was ultimately very frustrating and we decided to move on.
Just Okay: Playtex VentAire Playtex BPA Free VentAire ADVANCED Wide Bottles 9 oz - 3 Pack (Colors Vary)
The second type of bottle we tried was the VentAire. We stuck with the wide nipple to hopefully continue to support breastfeeding. Luckily for us, though, our baby adapted really well to different types of nipples and didn't really have more trouble latching after switching to primarily using bottles. The nipple shape may be a bigger issue for some babies. We liked the flow of the VentAire better since it seemed more consistent. However, the nipples were constantly getting clogged! Some occasional clogging is inevitable if you're using formula, but we found ourselves having to unclog before almost every feeding, then sometimes in the middle of the feeding as well. It was frustrating to us and to our baby when her meal got interrupted.
Our Favorite: Dr. Brown's Dr. Brown's BPA Free Polypropylene Natural Flow Wide Neck Bottle, 8 oz - 3-Pack
The Dr. Brown's have definitely been our favorite bottles overall. The flow of the Level 1 nipple was very consistent and when our daughter turned 3 months old we switched to the Level 2 with much success. It is very rare that we have a clogged nipple or a leak, although those things do happen once in a while. It is a little bit of a hassle to clean the extra parts, but the dishwasher racks are very helpful with that.
A note on gas:
Both VentAire and Dr. Brown's claim to help reduce gas and spit-up. I have no idea if either made any difference with our daughter. She spat up sometimes before we switched to these bottles, and she still spits up sometimes now. As our pediatrician says, "It's what babies do." People who have had babies with severe colic or other issues may have been able to notice a bigger change due to the bottle design, but we didn't see much.

What to do so the bottles don't leak Feb 19, 2012
By Seattleite My baby likes these bottles. She almost never spits up, so Mommy likes these bottles too. True, there are a lot of parts, but I'll take the extra hassle with the dishwasher over cleaning up spit-up every feeding.
When I first started using these, they leaked constantly--I'd tip them over to feed, tip them back upright, and when I went to tip the bottle back over to feed the baby, milk leaked out all around the white bottle collar, soaking the baby's chest and making a mess. What the heck? After talking with Dr. Brown's customer service line (great service, highly recommend) and a bunch of trial and error, we learned the technique to avoid leakage.
The thing that causes them to leak is any liquid or condensation getting inside that two-part valve assembly. Here's how to avoid it:
1. When washing the bottle parts, make sure to get all water out of that tan pyramid-looking part. A bit of water can get trapped inside the empty space that runs through it. Whatcking it against the counter a couple of times does the trick--even after you take them out of the dishwasher hours later.
2. If you warm up a bottle, heat it with ONLY a cap on the bottle. -- keep the nipple, collar, and valve assemble separate.
3. Dry off the bottle, especially the ridged part where the top screws on.
4. Assemble the bottle parts only after the liquid is warmed. And after you walk over to your baby, tighten that white collar once more.
5. If you need to warm up a bottle with the silicone nipple and collar in place, use a towel to dry off the screw-on parts of both the bottle and the white collar.
6. Never, ever, ever heat the bottle up with the valve assembly in place. Warming liquid will force condensation up into the valve, and then the bottle will leak. Never do it.
That did it for us. We haven't had one leak in a month. Hope that helps.

From a mother of 5...Dr.Brown's are a must! May 03, 2009
By Mother of 5 I decided to try Dr. Brown's bottles with my baby since my previous baby had gas issues. For the first 5 months my baby did have gas and I had to use gas drops.(I believe its because I use powder formula. The country I'm living in only has powder.My first 2 babies used concentrated formula & had no gas.) If I hadn't used Dr. Brown's however her gas would have been worse. I know this because at 4 months, when I needed to change the nipples, I opted to change to another popular brand. (Because I live overseas I would have had to order them on-line and wait.) With the new bottles her gas became worse. I decided to order them and I'm glad I did because when I started using them there was definetly an improvement Now at 6 months she is gas free, but only because I;m using these bottles! I recommend these bottles to everyone!

Really Worth The Trouble? Oct 26, 2011
By mossyshotty I originally purchased Dr. Brown's due to the great reviews for them being as close to breast as possible. They are, however, a huge hassle to clean. I hand wash all our bottles daily and the additional two pieces inside are ridiculous to clean out. The little pipe cleaner brushes they come with get dirty and rusty really quickly. Even the Dr. Brown's bottle brush (which I purchased too) does nothing special to help clean these proprietary bottles. Does the special airflow system make a difference? Hell if I know...my baby still burps and spits up - with no basis for comparison since spending another $50+ on another brand and batch of bottles is silly. That's all just my frustration - I don't have the time or money to spend debating cleaning and cost of bottles. However, to Dr. Brown's credit, my baby is being effectively fed. He's still riding high at the 95th percentile for length and weight. The bottles are doing their job.

Do not buy these -- stick to the old style 8 oz bottles Feb 27, 2012
By A. Gordon These new Dr Brown's bottles are unusable. We have twin babies, 3 1/2 month old. They are very happy with the regular-shaped Dr Brows (we have them in 2, 4 and 8 oz) but refused to drink from these new bottles. You should also note that the pieces (insert tube, libble, cap...) in these newly-shaped bottles are incompatible with other Dr Brown's bottles, rendering your existing investment useless. .
