These bottles are great! My daughter is exclusively breast fed, so I was worried about finding a bottle that wouldn't cause nipple confusion. I tried these bottles and was very satisfied. The nipple on the bottle worked well for latching, the flow wasn't too fast and they inner straw made burping much easier. The price is a little high, but overall a fed baby is a happy baby
We liked the Dr. Brown bottles a lot. Our only complaint is that there are so many pieces. It was such a process to clean these each and every day. However, that said, I know that the pieces are what keep babies from getting gassy and I can definitely say our baby was never gassy from her bottles.
This bottle was recommended to me by my pediatrician since my newborn had bad gas. She would turn extremely red and strain from the gas, she looked like she was in a lot of pain. Since I started to use these bottles I have a much happier baby and she doesn't look like she's in pain anymore.
