Okay, okay draw on the windows

Have you seen these? If not I recommend you go out and get a set. They are Crayola Window Markers. I bet the tub crayons would work the same. They are a great way to let will color with minimal mess. He really likes them too. I will warn you that they do get on clothes and skin but wash out easily with just water. One thing I have thought of as a draw back to these is that it doesn't really teach him appropriate surfaces to color on but I guess we will get past that issue later.
