#35 Say “NO!”
Basic, ages 2-18
When children are unsure about how serious you are about a limit, get their attention and give a calm but firm signal of your disapproval (sometimes called The Look).

Examples:
Father and his young son are visiting the mall. The little boy starts begging for a toy he sees in a toy store display. No, the father says, I will not buy you that toy.
Mother sees her preschooler take several cookies right before dinner. She gets his attention and gives him THE LOOK. He puts the cookies back.
