Oh I feel your pain. My DD1 is exactly the same. Rarely eats dinner no matter what we do. We even do the nothing after if you don't eat. Rarely works. But she is still growing, and sleeps well. She really likes her breakfast though! I am hoping she will grow out of it, but I refuse to stress about it.

ETA and she is also very stubborn as well. Can't make her do anything she doesn't want to.
