Well you are two up on me with the little people but I can tell you what I do with my dragon when he puffs fire into my face...
I kneel down to his level, talk real low, so low that it's a whisper and I ask him why he's so mad. Or what can I do to help him be happy. I try to put him in control because thats what this is all about - they want control!
If that trick is not working, I talk to myself about fun things I'm going to do - Oh, I think I'm going to get a few paint brushes and paint a picture. Oh, I can get my shoes on and find sticks or cool looking rocks outside. This distraction works almost everytime.
Timeouts for the parent: When misbehavior starts and it looks like it’s a power struggle, stop whatever you’re doing and walk out of the room - put your ego aside; it’s not about winning, it’s about extinguishing the behavior (from Children: the Challenge). “There is no show without an audience.” I have gone in the bathroom and shut the door. If it’s the car, I have pulled over and gotten out. I have reading material for myself EVERYWHERE to distract me and pass the few minutes of time I need to regroup!
Ask for a hug. Get down low, make a sad face if necessary and explain that you NEED a hug.
Question the child: (“What did I ask you to do?”; Should you do this or that?; and to redirect: “Would you like to do this or that?”; “How do we use the ___________?” fork, pen, etc.)
Review what happened at a later time in the day. Point out the good things about the day, point out one area you would like the child to work on. Remind them of the consequence as well (i.e. “I like the way you”…statements, but then discuss for example, whining/temper tantrums and the consequence that goes along with it).
I would recommend books but I can't imagine you have enough free time to read!
Good luck,
H.
