Our two year-old son, Brandon, is apparently dissatisifed with our current sticker inventory that we use to reward good behavior. The other day he pleaded his case to Christie trying to convince her that we needed a better choice of stickers. He began listing characters that he would like us to buy in sticker form. His closing argument was simply “I’ll poop on the potty for a Mack (from Cars) sticker.” Two years old and he is negotiating the terms of his potty training.
