The Avent bottles are great for a mom who breast feeds or bottle feeds.  I used them with both of my babies who were only fed breast milk.  They are very similar to the breast, so they help reduce confusion.  I also really like that they are easy to clean.  Just throw them in the dishwasher are you're ready for the next round.  I don't like to mess with liners because I think they are a waste and are too messy.  The Avent bottles also have an adapter to make the bottle into a sippy cup, and that worked great for my kids.  They are now BPA free, so with my next child, I will get a new set. ...
