Hi K.,
Congratulations on your pregancy! Are you going to find out what you are having, or let it be a surprise?
You've gotten a lot of great responses as far as which bottles are good... and I am sure you will probably get many more.
I personally have not tried Dr. Brown's, but it sounds like they must be pretty good. With my first I used the Playtex Vent-Aire bottles (they were ok, and my son did not seem to mind), with my second I used the Avent bottles, which I really like a lot. Like another lady said, they are the closest to the real thing, and they also keep the air out. Most likely, I will probably stick with Avent for my third child (due in February), or I might purchase a Dr. Brown's to see which one the baby prefers.
It is good to get opinions, but ultimately, no one knows better than you do which is best for you and your baby! Try one of each, and go with your God-given, motherly instinct. Between that and your baby letting you know, you'll be just fine!
Wishing you all the best!!!
I.
