My mother broke the code with my strong willed 5 year old. I was away and DD5 dropped something on the ground which Grammy asked her to pick up. Of course DD5 refused and prepared to dig in for a battle of the wills.

Instead of taking the bait, Grammy said in a stern voice "Don't you DARE pick that up!" So DD5 immediately picked it up knowing she was playing a game with Grammy. We've had numerous requests for the "Don't you DARE" game ever since and it's helped us get her to cooperate by being "uncooperative." grin
