My go to bottle This was my go to with my daughter! They helped prevent gas. I did receive some that leaked but the company sent me new ones. There are several pieces to clean but it really is worth it.

Good Ok, so originally I hated these bottles because they leaked all over. But my baby has had really bad gas and I got desperate. How could there be so many good reviews if they all leak? What am I doing wrong? Turns out, the fill line "do not fill above this line" is obvious once you look for it. The directions "hold at 45 degrees and keep the vent end out of the milk" is much less obvious. Both are definitely complicated to figure out when you haven't slept properly in months. Bottom line is that they really reduce gas... but be careful how you hold them and fill them to feed you baby. If you're careful, they work like a charm.

Our first babe used these so well we decided to try them with our twins. Nearly 9 months later we are still only using these bottles. All three of our kiddos are so different with their feeding preferences but these bottles worked great for them all!

Best bottles These bottles have prevented all four of my children from ever getting an ear infection. They do have a couple extra parts that are needed to push air away from baby, well worth the extra steps.

Worth the hassle of extra parts. We love our Dr. Browns bottles. I'm a true believer that these reduce gas and colic as neither of my kids suffered from it. I will say, it's a big pain in the rear to wash all of the extra pieces, but in my opinion, it's well worth it.

Good bottle set with a great price This is a great starter bottle set. It's a great value price wise and it's nice that it comes with 2 different sizes. My daughter had no issues with this nipple. It's also easy to find anywhere you might register which is a bonus for family and friends trying to shower your new little one. I would definitely recommend to both new and experienced Moms.

I love these bottles. My granddaughter does not get gas and tummy aches using these bottles. When we used other bottles, the baby had trouble sleeping due to being too gassy. These bottles make a baby happier and comfortable. These are the only bottles we use. They are the best!!

Not the best I got these in hopes that they would work for my baby. But everytime I used them and my daughter drank out of them they leaked! And I only had 4 oz in the 8 oz bottles

less gas I absolutely love these bottles. My baby has less gas and hiccups when I use these. They are easy to clean and assemble. Great product.

Like!! I like these bottles because for one they are versatile and for two you can properly make a full oz bottle with them unlike most others that do not leave enough room for the formula once the water is inside.

Life changing!! I am that annoying person that walks up to pregnant women in the bottle aisle to tell them that this is from up above. I will never use another bottle. It's like magic! My first one had collic horribly, I started using these and I haven't looked back. Especially since they grow with your child!

Wonderful! All my kids loved Dr Brown bottles. It was the only one that would not give them gassy tummies! I tried every bottle but we would always come to Dr Brown! They are great!

Yummy for their tummy Nieces were raised on these and the only time one had a tummy gripe was after the doc brown bottle days and consuming lots of broccoli. These bottles seem to eliminate bubbles and make the feedings heavenly.

Loved these bottles My favorite baby bottles. My son loved them and drank out of them right away with no issues. I only read great things about them! I did experience some slight leaking with them, however. When I would take out the inside piece that helps eliminate bubbles, it would stop leaking so I just quit using those parts.

My son is exclusively breastfed and this is the only Bottle he will take . We use the glass bottles
