Removing a reward instead of threatening a consequence
Interesting twist on behavior modification, from Jill:
I read this on another blog in the comments, so it isn't my idea BUT I plan to use it quite soon! Removing the carrot instead of threatening the stick...
To successfully grocery shop with children, first put into the cart something they like to eat. It can even be something you usually buy anyway; it doesn't have to be special as long as they think its special. If they misbehave, threaten to put it back on the shelf. If you really do put it back when they break your rules, they'll quickly learn that the treat won't make it to the car, let alone the house.
