Kids threw blueberries on the floor during lunch and I said they needed to pick them up. They pretty much refused though I offered them several choices for receptacles to put them in. I took their lovies and put them in timeout and said they were staying up till the blueberries were picked up. Then I set the timer for 8 minutes and said they were getting a slap on the leg every time it went beep beep. So far, the blueberries remain on the floor, they've gotten two slaps on the leg each and the timer is going again. They are pretty much in hysterics and alternating rage and refusing to pick up. They get distracted and start to play but the sobbing starts again when I take them back to task. What would you do?
