Two-year-old Rumiko started whining at the grocery store. The best way for her parents to extinguish this behavior is to praise her when she is NOT whining at the store and leave the store .

The correct answer is : consistently / every time she whines

Explanation:

Whining is a normal way in which children express themselves when they are cranky, hungry, tired or uncomfortable. It makes them feel powerful. To break this habit you have to refuse to let it bother you and give praise where praise is due even though it is awkward being so effusive, but the behavior will decrease.
