I don't have children *That is my little disclaimer* however when reading your post your examples of your children made me think of a book that a read awhile ago, "Positive Personality Profiles" by Robert A. Rohm
" Dominant type is equivalent to the old Greek
choleric "
"The 'D' type s very
demanding . The seldome take "no" for an answer. A "no" to them means "Ask again later!" If you stick to your "no" they will be thinking of a way to go around you. Ther are not being rebellious - they just have so much drive and determination that they want to keep going. "
"Research seems to indicate that only about 10% of the general population has this type of profile."
"When I first became interested in personality types, it was almost out of desperation. It seemed to me that my oldest daughter, Rachel, was getting more and more out of control. I found myself constantly asking, 'What is the matter with my daughter? Why is she so stubborn and hardheaded? What happened to that sweet little girl who used to ride on my back?"
"Because you have a high "D" type daughter you need to parent her differently. High "D" must have challenge and control. These are their basic needs. When you say to her, "Rachel you need to go to bed by ten o'clock,' she hears something enitrely different from what you said. Rather then hearing, 'You need to go to bed by ten o'clock, ' she hears, 'Do you want to fight?'"
"I thought to myself, "Wow, that must be right! She likes to fight about everything! So that night I thought I would try it. I said to Rachel, 'Tonight you can go to bed whenever you would like. Ten o'clock is the limit, but you choose.' She looked at me and said, 'okay!' And that night at ten o'clock she went to bed...and I picked all my teeth up off the floor!"
Sounds to me like you all have D type children.

Good Luck!
