It is after we try the charts with the stars, the timeouts, the “ignore and isolate” strategy, that we tell Sila about our other son, Bila. Bila, we say, is our first son. He’s your brother. My brother? Yes. He lives in the backyard now. In the hedges. And he can never come inside. Why can’t he come inside, Sila wants to know. Well honey, we say, he was so bad, just a bad boy. We made him sleep outside until he straightened up.
