Some kids are smart -- and sly. Instead of finding a hiding place for broken toys (dishes, small appliances or anything that belongs to dad) in the house, they just open a window and pitch the evidence in the bushes. If your landscape looks like something out of a Tarzan movie, it could be a decade or more before the loss is ever discovered. When it is, your child -- now a teenager -- can blame it on a burglary gone wrong. You really have to admire that kind of ingenuity.
Here's another thought: If you have very young kids, opening a window may be too much of a challenge, so try looking in your floor vents for small items instead. We don't know if kids think half-eaten crackers, carrot sticks and broken crayons just biodegrade when they're pitched in a floor vent or not, but it's one spot that can yield a bonanza of discarded objects and moldy food.
