Situation: N is relentlessly tormenting K by mimicking and making fun of High School Musical 2 while she was trying to enjoy it. This eventually leads to shouting from K, which wakes up the baby. That's bad news.
Creative Discipline: N is granted his desire to imitate HSM2, but his tormented audience member must leave the room. All of a sudden, it's not so fun to sing along and mock HSM2. After some histrionics from N about how horrible his discipline was, he did complete the assigned discipline. I may have even seen him crack a smile.
The jury is still out on whether this was effective or not. I hope it will be helpful because I'm exhausted by the amount of sibling squabbles we're seeing at our house.
