Youngest Son asked to be excused from dinner tonight with eating much. I told him he needed to eat some more food. And he did. So I excused him from the table.
About 10 minutes later he asked if he could have a snack. I told him "no, if you are hungry now it is because you didn't eat enough dinner food, and you don't get a snack until bedtime." He tried a couple more times, but I stuck to my line.
About 8:45 he said he was ready for his snack. I had him turn the TV off and use the bathroom, and told him that after he ate he would go to bed. So he ate. Then he said "maybe I'm not ready to go to sleep yet."
I told him that he had just had his bedtime snack, so now he had to go in his room. If he wasn't sleepy he didn't have to go to sleep, but he had to stay in his room. He went in, and didn't come back out. Apparently he was ready to go to sleep.
