Young Rhinos have more than enough sass to exhaust anybody. Acting crazy is a help, but Mom has only so much patience. The Rhino Solution is of long standing: Mom designates an area, referred to as a Tantrum Corral, in which the Tot can holler and wriggle and spasm without limit. BUT, no leaving the Corral until you quiet down.
It’s surprising how long some Tots can carry on. But after a while, or a day or two, the Tot gets hungry. That helps. No snacks til you’re calmish. A tried-and-true method of Behavior Modification.
