Do you have a back-up meal ready in case she/he doesn't want what you give her/him?

I sometimes have 5 different things on hand. This morning was the worst...she wouldn't eat prunes+yogurt (2nd day in a row she's refused it, even though she happily ate it for a few days last week), so i gave her thinly peeled pears and mangoes. I tried to give her some of my oatmeal, but only took 2 bites before giving me the "no way" grunt.

What do you do?
