I use avent bottles.... I used them with my first and will with this one too!
I had great success with Dr. Brown bottles with my first and will be using them this time as well. I mostly breastfed, but she had no problem going from bottle to breast.
U should use which ever bottles your baby can adjust too try a few different kinds just to get a feel for it and bottles with the bags gives babies less chance of getting air in their tummies so those should be a nice one to try for a less fussy baby
