Doorknob covers. Nothing makes you feel like a monkey faster than fidgeting with a doorknob for five minutes.
Bought Jaxon crayons and a coloring book last night--kept him busy for 10 minutes--long enough to clean the kitchen without him underfoot. I might add that it took him about 30 seconds to figure out how to remove the crayon from the holder and stick it in his mouth, but they must not be very appetizing, since he didn't finish the job. Some crayon actually made it on the coloring pages, and now I have his very first artwork to hang on the refrigerator!
