Lately I've had to start using my "mom" voice. Example: Last night on our way home from school/work, Elliot was chewing on a toy that I had told him a million (yes, a million) times not to.
Finally, I had had enough. And spewed this:
Elliot James! If you don't take that toy OUT of your mouth RIGHT NOW I am going to take it away and throw it out the window!
His response? Stared at me, wide-eyed, while slowly taking the toy out of his mouth. Job well done, mom. Job well done.
