[Insert sibling spat here.] This calmly-stated conversation followed:

Ian: Elijah, I’m sorry for hurting you. I should have used self-control.

Elijah: It okay, Ian. You don’t have to use self-control. If you want to hurt me, you just have to ack me if is okay to hurt me.

Ian: All right…but next time I feel angry, you’d better prepare yourself to get hurt, or else say something to stop me and then I will go play on the pillow [our giant bean bag chair].

It’s a work in progress, but certainly preferable to the more-frequent crying-tattling-mommy-please-destroy-him episodes.
