Dr. Brown's Natural Flow BPA-Free 8 oz. Bottle- 3 packDr. 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. The air is then channeled through the internal vent system to the area above the breastmilk or formula.
what parents are saying
I went through MANY different types of bottles with my baby girl and this is the only bottle that almost completely eliminates gassiness! I wish I would have found them sooner! (Aug 21, 2014)
The saying goes “when baby isn’t happy, nobody's happy” and that definitely stands true when baby has gas. Que Dr. Brown’s bottles. With their vent technology designed to mimic breastfeeding and limit the amount of air baby can consume during a bottle feeding, they help to reduce gassiness, reflux, colic, spit-up and even burping. Parents love that they’re also available in glass and travel well.
The Catch: There are a few extra parts to this bottle, so be prepared to keep track of a extra pieces.

I didn’t notice a big difference in fussiness, but the NICU therapist recommended this bottle. Lots of parts to clean & little brushes included for this. Baby took to this better than other brands.

I tried one of these bottles, and I think it was great for my gassy baby. I ended up using Comotomo bottles mainly, but this bottle was used occasionally. I would probably use again with my next baby.

We use the wide beck Dr.Browns bottles (green insert) and our daughter absolutely loves them. Great for my reflux baby as the vent technology limits the air consumed. There's a bit more to clean!

I received this in a target goodybag when making a baby registry, and good thing I got to sample this because my baby didn't like the nipple - had trouble latching properly - and it has too many parts

Love these bottles for colicky babies! The venting system allows for air to escape the milk so that your baby doesn’t swallow air. These are harder to clean, but worth your baby not having painful gas

They were OK, but we used the Kiinde system and then didnt end up using the bottles as much as the Kiinde bags. She did OK with them, but transitioned to cups quickly. We ended up with a lot of bottle

The hospital sent us home with several of these when we left the NICU. I find them to be a bit leaky, and aggravating to clean. I do appreciate that they have nipples that accommodate preemies though.

My daughter Loves them, they are pain in butt to clean but only bottles my ldaughterone liked. Make sure to use this little brush they come with and clean rubbery part good, they can get moldy inside

I used these at one point with both of my kids and I thought they were a waste. They're so annoying to clean and I didn't think they were really that much better with gas and reflux. Plus they leaked.

The bottle is a lifesaver for colic, and helped my son sleep but the only downfall is cleaning all the parts. I hate cleaning the parts but it helps my son eat better. So happy baby, happy mommy

I know everyone loves these and they’re super popular but I haven’t found them to help with gas or colic whatsoever. They also leak my precious liquid gold everywhere which angers me to no end.

These were great in decreasing the amount of air my baby would take in and therefore reducing gas but they were cumbersome to clean with all the parts and they often leaked which was frustrating.

Easy to assemble. I used this for paced bottle feeding while I tried to get my daughter to latch. Lots of parts to wash though. Fits Medella Pump, so I use one to help remember which one was my left.

We had to use These as our preemie was sent home using them. HATED them. If you love washing a Million Little pieces and Little holes These are the bottles for you. They are HOTEL for mold too.

They seem to work okay.. but the leaking is driving me nuts. The caps don’t click all the way on the top, so if you put them in your diaper bag, water leaks out. Makes for a messy bag & wastes water
