I have interest in cooking and eating...and also study nutrition and chinese nutrition....that's why...
Em...my suggestion is, no need to force, but let her see you (parents) like eating and enjoy the time to eat with her, she will imitate you and thus yr demonstration (with a funny face) is more important than force her to grip.
I will remember make "funny face"...her case is a bit similar to "hoi" "Him"...and can you imagine she did not use teat for milk since she was 5months?!
