HI A.- I also had 3 out of 4 kids who wouldn't take the bottle- we just went straight to a sippy around 8 months with water only and then if I needed to be out during the day we put in some breastmilk and they were fine with it.
If you don't mind there is no reason a baby has to take a bottle. I realized after I had my third and fourth that the 1-1.5 years a baby bf goes by quick when you look at the whole childhood!
Good Luck,
B.
