Hiya,
I was at a bf group the other week with the same problem. My dd wont take a bottle of either ebm or formula.
Aparently the bf buddy told me I'd probably missed the boat and that she'd take it when she was good and ready. Not what I wanted to hear, as I'm trying to stop bf. I've had enough now, but alas, my dd won't let me.
Think you have to get the baby on the bottle at about 3 weeks in order for them to take it. Or wait till about 6 months. Thy're mouths change along with the way they move their jaws, making it easier to change from bf to ff.
I know this is not what you want to hear, but after spending a fortune on as many different bottles, teats, cups, I've resigned myself to me having to wait till she's ready.
My ds was very similar, but took a bottle alot earlier than my dd.
Hang on in there and it'll come good. I think I'm writing this convincing myself as well as trying to help you if that makes any sense.
Good luck and let me know if you get any joy.
Clury
