One thing that I wish I would have known before we started using bottles is that they’re not “one-size-fits-all.” Your baby might get gas from or simply not like a certain type of bottle. In fact, you might end up trying several different bottles before finding the one that is best for your baby.
We tried Avent bottles first, since I had also purchased the Avent Isis pump. Even though they’re “anti-colic,” C swallowed a lot of air while using them. I purchased a set of Tommee Tippee bottles on Amazon, but they took a while to arrive (time goes slowly when your baby is uncomfortable!). In the meantime, we wised up and decided to purchase one bottle each of Born Free and Dr. Brown’s bottles. Both of those were recommended to us by people we knew.
The Tommee Tippee bottles work for C; but, we think they would have worked even better if he went straight from breast to bottle with those instead of using the Avent in between. The nipple on the Tommee Tippee is designed to simulate the breast.
We still have the Born Free and Dr. Brown’s bottles in our rotation and C does well with those, too. They are also good for reducing gas.
Bottom line: I would have purchased one bottle of each to see what C responded to best. I would highly recommend doing the same – bottles are expensive!
