With DD1, we never got her to use a bottle, so this time around with DD2 we just haven't bothered to try. I went back to work today (DD2 is 8 months), and DH was home with the baby.
For cup feeding today, he used a ramekin! It's got a square corner, so much easier to direct the milk to DD2's mouth than a regular cup.
Just thought I would share in case anyone finds it useful to try.
