Perfect!

I used these bottles with my son - both classic and natural. Super easy to use and clean. I did't have any problems with leaking. Nipples and bottles were on sale quite often. would recommend to any new parent!

These are the best there is

We have tried many bottles for my son, and these ones are the ones her prefers. No colics, no gas. Moreover, the 9 ounces are a perfect amount for his tiny tummy. Quite expensive in my opinion, but totally worth it!

I love the Avent bottle because of how easy it is to clean. My son who was breast fed for a year took to it without any issues. I got the classic nipple.
