Noah saw a marble set and really wanted it and I really wanted him to go to bed without sneaking out and down the stairs to "help with the dishes," so We struck a deal; he would stay in bed after he was kissed goodnight and I would get him a marble set.
I took a video of him using it and asked him how long he had to work for it. His reply, "like seven years." Yes, something like seven years.
Next step is getting him to stay in his bed all night long. I'm going to have to start saving up.
