I use Advent Classic. Love them! I use the short/fat ones they fit best in the diaper bag. Easy to clean and love that they don't cause gas.

Love the Avent bottles!!! I also used Dr. Brown with my first.

I LOVE mr.brown brands

I used avent with my son till he was one year. I never had any issues, I used plastic classic bottles the first few months then switched to glass natural just because I don't like that plastic leaches chemicals. I plan on using them again with my second i think they are the best, easy to clean and doesn't cause gas.

My son loves the avent bottles!

My daughter LOVES munchkin , but there pricy and I can't get her to take any other bottles lol
