Ed,
Yeah the peat shower is fun for him, but not for the clean-up crew

You try getting peat out of diapers! If he can't get his chubby fingers on the scoop, he'll just grab whatever he can.
We just got him some gardening tools of his own to get him out of trouble, he's been scooping earth from one part of the garden to another.
Just have to make sure that we hide the mini-hoe that my mom uses, he's been claiming it as his own - it's a bit dangerous for kids his age. That kid is in LOVE with any rake, hoe, broom, mop & dustpan, fact is anything with long handle he sees as potential toys. Janitors with their pushcart are his hero!
Kids, how do deal with them? Just when you want to reprimand him, he looks at you with this big shiny eyes (not unlike Puss in Boots in Shrek!) and gives you this huge smile that will get him out of trouble everytime!
