ML,
Your daughter sounds just like my 5 year old! He doesn't like to do his chores either! He is also very dramatic, when told to do something he doesn't necessarily want to do he has been known to fall to the floor in a heap and just lay there crying about "I'm so tired!!" or hes the king of excuses about why he should't have to do anything around the house (his only chores are to unload the silverware tray from the dishwasher, take care of his folded playclothes, brush his own teeth morning and evening, and to generally pick up after himself) OH and this is my favorite one- he will try to stare me down, state very unemotionally that he hates me and that all I do is boss him around! (I really have to keep myself in check not to laugh at him- he is so obviously trying to push my buttons!)
What we do is not engage him. When he says he hates me I just tell him "oh really? Thats too bad, because I love you" and leave it at that (and don't take it personally, hes just trying see what he can get away with). I then start counting 1 2 3 slowly. When we get to three, he loses something. A toy, a trip to Grandmas (oh he hates that! Grandmas house is fun!), maybe something fun his brothers (he has 4 brothers) are going to get to do, sometimes we all have a treat in the evening and he may miss out on that. I usually tell him what hes going to miss if I get to three. If he acts like he doesn't care about what is going to get taken away from him, I have been know to keep adding to the list until hes motivated to be cooperative.
Don't be afraid of being "mean". My son tells me that when he doesn't get to the things that he wants to do. Be consistent!
They know when you are bluffing and when you mean business. This will take 2 or 3 times of missing out on stuff before they take you seriously. But now when I count I rarely get to 2, he shapes up pretty quickly. Its easier on him to do what is expected of him. It is just his personality. He is a button pusher, and dramatic, and always testing his limits! But he can be the sweetest little boy when he wants to be. Good luck and I hope this was helpful.
