I have a very strong-willed dd3 (last of 4). She is 5 and a half. She has a core of steel and nothing gets past her, which means she will not fall for any strategies or games I used with the others to deflect their attention from the fact that they weren't getting their own way. If she badly wants something, or to be allowed to do something, or doesn't do what I need her to do, and I refuse or suggest alternatives, I am met with a cold statement of her wishes, sticking out of tongue followed by threats ("I'll kick you, I'll just do it anyway), and either wild screaming or an attempt to carry out the threat. This happens almost every day, sometimes a few times a day, has to be experienced to be believed, and I am running out of ideas.
Now, my husband is a Presbyterian and believes in smacking. I don't, and am worried about her pushing me to the limit so often as my temper is quick.
What would you do?
