In our house, we call the picky eaters "hungry".
Psh. Who cares what you call them? What matters is how you deal with it. In my
house, the rule is "you don't have to eat it, but you do have to taste
it". Only dinner eaters get any dessert. Non-dinner eaters have to wait to
see if breakfast will appeal more. Tasters get the option of "buying"
their own dinner from the refrigerator...after the rest of us are done eating.
