Brooke lies on the floor, lost in imagination as she hums and flies a Strawberry Shortcake figurine through the air in front of her. She doesn't see it coming. No one does. Kerrington, the baby who has committed no wrong up to this point except for diaper explosions, crawls toward her and performs her first act of violence.
She lifts her still-pudgy baby hand and whacks Brooke's forehead surprisingly hard.
They look at each other, stunned. Brooke yelps, sits up, clenches her jaw, and lifts both arms in protest.
I quickly touch her arm in restraint. "Brooke," I remind. "Don't hit her back."
She looks at me for one moment. "What about hitting her head?"
