So, Tater's behavior is progressively worse: this year is worse than last, last year was worse than the one before. It's the kind of behavior that if we saw some other kid doing it we would furrow our brows and say, "That kid needs a spanking." I know. I know. I just uttered the unspeakable word. When you have recovered, read on.

Our guiding book
Transforming the Difficult Child
(which does not advocate spanking) recommends that we acknowledge that all emotional reactions from parents are -- from a kid's perspective -- pay-offs. Negative or positive, they are the desired response.
We especially see this when I am doing anything that precludes giving Tater my attention. She would like to have non-stop undivided attention. If I am not available for positive attention, she will deliberately trigger negative attention. Literally, it will go like this:
Me: Tater, I am not available for 20 minutes. If you interrupt me, you will have to wait on your bed.
(20 seconds pass -- she interrupts.)
Me: Okay, time to wait on your bed.
Tater: NOOooo, I don't want to. (Screams, rages, won't go to her bed, throws things, screams that she hates me and that when she grows up she will come back and stomp on my stomach.) Pretty much does whatever she can think of that will get me to physically move her to her bed and/or return to the room she is in. When the mean screaming doesn't work, she will sob that she needs a snuggle.
Oh, she needs a snuggle. I'm supposed to deliver that right? No! I used to, but I've smartened up. Look at this from her point of view.
Mom says she is not available. If I act up, I'll be sent to sit on my bed but if I don't go, she'll have to take me (attention) and if I scream something loud enough or long enough or mean enough she'll come close my door and windows (attention) and when I stop screaming she'll pop in all smiley that I stopped screaming and I'll get a long snuggle and I'll have her attention.
And this is pretty much wrecking my life. I can't stand the screaming 2-4 times a day, an hour at a time. I can't keep my cool, so even if I am calm and neutral with her, the anxiety emanating off of me for the next several hours is a tremendous pay-off for her. How powerful she must be to jangle her adult so thoroughly.
And how can we sparkle and dote upon her for compliance when there isn't any? For this, sparkling and doting, is (according to our book) the path to happiness: help her see herself as someone who can be pleasing.
This morning:
Tater comes in all scowling and snarling because she doesn't like part of the day's plan.
Me: Please leave my room. You may come back when you can be pleasant.
(You need to know that our bedroom is the long-established safe house for adults and pets. The children may be in there by permission and at our discretion. I have to have somewhere to cool off.)
Tater huffs out in an indignant and surly manner.
Me: Please go sit on your bed.
Tater objects and back-talks and argues.
Me: Tater, I cannot allow you to behave in such an ugly manner. Please come in and get your spanking. (Now, before you think this is so harsh, remember that past experience causes me to believe that her screaming will escalate into a huge drawn-out long ordeal and my goal for the day is to take the kids swimming with their cousins.)
I give her two swats in a very calm neutral manner.
Me: Please go upstairs quietly and sit on your bed.
Tater screams.
Me: Tater, I cannot allow you to behave in such an ugly manner. Please come in and get your spanking.
I give her two swats in a very calm neutral manner.
Me: Please go upstairs quietly and sit on your bed.
Tater: Stomps and kicks and scowls.
Me: Tater, I cannot allow you to behave in such an ugly manner. Please come in and get your spanking.
I give her two swats in a very calm neutral manner.
Me: Please go upstairs quietly and sit on your bed.
Tater goes upstairs quietly and sits on her bed.
Twenty minutes pass. Nothing is thrown. No mean words are shouted. It is amazing. Garbanzo is amazed. I am amazed.
I call her down. I lavish her with praise and admiration for using her strength (she likes power, remember?) to go upstairs quietly and to sit on her bed. I do a silly happy dance. She giggles. I hug her. Garbanzo high-fives her. I lighten an unpleasant obligation that she is carrying for the day. We eat breakfast together. Life is good.
I know the spankings are so questionable. I question them. But in this instance, they were able to derail the Tantrum Train, so she could experience what it might be like to obey and please Mama and received positive energy and have a nice day.
I like the train analogy. If she is on a speeding run-away out-of-control train heading for wreck, and I can shove her off the train, I'll do it.
Right now she is pleasant and helpful and singing.
