I recieved a ton of AVENT bottles for my baby as a gift at my shower. I was really excited to use these bottles. They were small and best of all, clinacally shown to reduce colic. My first born suffered from colic and I did not want another baby having to go through the pain of colic. These bottles leak like a sift and gave my baby so much gas!! Not only did I have to hear my baby scream from be hungry, now he was soaked from this bottle leaking on him and he had gas from all the bubbles. 

After 2 weeks of using AVENT, I decided to try Dr. Browns. A huge improvement! My baby was DRY and happy....
