Babs usually skips dinner. She sits with us, but will tell us how nasty the food is, or that she hates it. But rules are rules, and the rules of our house are that you have to eat dinner if you want something else to eat later. Her dinner often sits cold, waiting to be eaten just before bed in case she decides she needs a snack before she goes to bed. (But, if she likes dinner, she eats plenty.)
Last night she yet again did not eat dinner. Just before bed she really wanted to eat, so I showed her the dinner she did not eat. She managed to eat it, and then she got her desired banana.
I warned her, it's a little green... "That's okay, I only eat the inside of the banana."
