I just came about these pictures from just after Christmas. We had 'B' week at our house and spent a day with boxes. Luckily the holiday and the massive amount of diapers we go through provided us with many (however local appliance stores will provide you with free large ones if you ask). We made a maze, house, tunnel, and towers.
Why do we worry so much about the toys??? We really should buy gifts based on the sweetness of the box it comes in!!!
