My 24 month old son has a swallowing disorder. He is required to only drink from these bottles with a stage 1 nipple(no sippy cups, straw cups, or other bottles). They really do help him swallow better, without aspirating and coughing. My least favorite thing about these bottles are all the pieces to clean. To my son, these bottles are a true lifesaver!

I used these with my second child after trying about 5 other brands this was the only one that he didn't get gassy from. Only reason I'm giving them 4 stars is they are a pain to clean and we did have buy extra brushes because I lost them all the time.

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

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

I used these along with a few other brands for my daughter. I wish I had them when my son was a baby, he had colic. The main reason I didn't use regularly was the price. I have no help from either father of my 2 kids so I don't have the funds to spend on higher priced items. One other thing is that they are so plain. I have always liked the cute designs on baby bottles. =) But as for quality and helping with gassy babies, Dr. Browns is one of the best!

I like these bottles. They worked for my newest baby who had gas issues later in his months. I did notice they leak on occasion and are a pain to clean. I used my dishwasher for these to make it easier. Lots of parts, lots of crevaces to hide gunk. But its worth it because they do help those gassy babies tummies and if anything relieves my childs pain, its worth every pain in the butt moment!

I used these bottles with both my kids. I felt comfortable that they were doing the job of keeping the extra air out of their tummies. I did try a regular bottle and it kept collapsing. I know there are a few pieces to clean but it is totally worth it for a baby with acid refulx. Seems alot of babies are born with this problem nowadays.

my son had severe acid reflux/spitting up, etc. although the doctor brown's did not cure the issue we did see an increased improvement when he used those as opposed to the other bottles.

Great bottles! The only bottle my baby would take! Several parts to wash but worth it because it limits the air my child takes in. Hold up well with many washes.

These bottles are awesome! When my son was born in January 2010 we started out using other bottles but switched to Dr. Browns when he started spitting up a lot. They helped so much. The only downside is they are a pain to clean.

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.

The only bottles I could use on my second daughter. Definitely worth the extra cash on those. The only downside was the cleaning. There was so many little areas for gunk to get stuck into. Took a bit more time cleaning them than traditional bottles. But again, all worth it!

I used these bottles with my last two kids! Absolutely love these bottles. My last two had no colic didn't spit up and were not fussy. I used pipe cleaner to clean out the inside piece though it last longer.
