During a creative period, difficult child managed to dump an enormous bucket of legos and another bucket of Ky'nex all over the family room floor. He was on his way outside to play when I told him he needed to first clean up. He ranted about how he wanted someone else to do it. When he figured out that it wasn't going to happen, he said I am only cleaning up the legos. Okay I said and then when you come back in you will have to clean up the Ky'nex before going back outside. Okay he said and I told him that it was a good negotiation. "I just negotiated?!," he exclaimend. "Maybe I can change my behavior."
