Every Christmas, parents expect to have to put together some toys. Its helpful when they include a list of the tools you need for assembly. But they really should label some toys, particulary toddler and preschool toys, "package disassembly required." A list of required tools would prepare us for the ordeal: sharp scissors, wire cutters, a phillips head screwdriver, and a bandaid. Also, a trashcan directly next to you to collect the two dozen wires and plastic bits that the baby longs to chomp on while waiting for her barn and little people animals to be released from midieval bondage.
