Now that I've tried these I would never use anything else. Solves the problem before there is one. If your baby has colic, acid reflux or anything tummy related I would give these a try. We first switched her formula and she was much better but still was concerning me that she was uncomfortable then with the addition of Dr. Brown's bottles she's been good to go and hasn't had an issue since. Couldn't think of a negative thing to say about them.

The ONLY bottles for us! We had "standard bottles" when my now 8 year old was born. She had ear infection after ear infection. We discovered these bottles and amazingly no more ear infections. The starw inside equalizes the pressure. It is the ONLY bottle we have used for our twins and only one ear inefction of the both of them and they are now 2. Now if I could figure out how to get them from liking them so much! They can be a bit of a pain, but if you rinse them out within 12 hours of use the straws don't get too clogged! We put the straws in the utensil holder in the bottom of the washer (and turn off the heated dry cycle) and the rest just goes into bottle baskets. Sure it takes a few backets to hold all the pieces, but still worth it! We thought about the playtex but you have to keep buying inserts and that just seemsed like a pain, especially with twins! We would have had to buy a TON of these!

I have these and they work great. They are a little pricey but that is okay because they work. I also like these because the nipples do not collapse on them. Good bottles all around but you will have to clean five separate pieces.

I have used these and ONLY these DR Browns Bottles for both of my sons ( now 4 yrs old and one is 4 months old) I can honostly reccomend every parent to use these bottles for their baby especially if your child has belly problems and The ventilation system is wonderful for those who are colicky! one small Con is the Cleaning process but it is so much more worth baby being happy with these botles than others that bring alot of air into the mouth of babies!!!!

These bottles worked wonders on my son that suffered from horrible colic .

DH took to these ones and they were great!! No gas problems, no leaking. (We preferred the wideneck ones for grasping purposes only) The only thing is that the collars are hard to clean after a while.., so we just replaced.

These bottles were a life saver!! My son had colic the first three months of his life and these were the only bottles that seem to offer some kind of relief! These were the only ones I would use until his colic was gone when he was about 4 1/2 months old. We still have these bottles and still use them.

These bottles are great for premies... since they have a premie nipple size. The positive pressure system is much easier for them since often times their suck/swallow reflex isn't fully developed. My baby still has gas, but I would think it would be much worse with other bottles. The main disadvantage is that there are more parts to clean... but it is worth it in the long run.

I used these bottles with my daughter as an infant and loved them. I wanted to use glass, not plastic bottles and these were perfect. I had no issues switching from breastfeeding to the bottle and back anf forth, and my daughter had no issues using these bottles, they seemed to help prevent air from getting in. The only downside is they have more pieces than other bottles, but they are worth the extra time it takes to clean themm and put together !

I love these bottles we had them for our fist child and we will have them for our second. We started her out on a different brand then switched to these. She was not near as gasy with these.

I used the glass bottles by Dr. Brown. I can't say they helped prevent colic and they did leak a little but I was pleased overall with usability.

I was recommended these bottles and I had to try them. I got them and I loved them. A little pricy, but you can change out the nipples with his age. The only cons I have is that they are much harder to clean then regular bottles and sometimes it tends to leak, but not too bad. They are awesome though :)

LOVE LOVE LOVE these bottles!!! They truly are a lifesaver. When my son was about 4 weeks old, he started getting colicy. A pediatric ARNP recommended them to me. Within 2 days, he was much better. no more crying after every feed. They are a bit of a pain to clean but so worth it. My son is now 4 years old and I now use the bottles with my 8 month old daughter.

My son and daughter-in-law used these as a supplement while nursing and after she stopped, I never saw my grandson with gas!

Works well to prevent gas buildup in a bottle fed baby but I find it difficult to clean.
