I have 4 1/2 year old daugther, who has done the same thing a couple of times. I felt it was a control issue. She is a very demanding child and wants her own way. After I decided it was a contol issue, I firmly informed her she can not ask for something, then change her mind, then change her mind again. If she asked then said NO it is NO. She cried for about 10 to 20 minutes at least, HARD and LOUD, but after I stood firm a couple of times the behavior stopped. Good luck it was not easy, she still will try me, on occasion, but this is a battle I have chosen to fight.
Well it is nice to know there are other parents with this same issue, but as I said this has been happening for over a year, not daily, but almost and there are days that it happens 3 or more times. I have tried this with no luck, but I do appreciate the response. I too have chosen to fight this battle so that hopefully when he is grown he can make a choice and live with it. But in the mean time I still feel crazy, if a little comforted to know there are others out there fightign the same battle
THANKS
