After a few days in the house, little boys tend to get somewhat stir crazy. The best formula we found for quelling this anomaly, was to use the stairs built in cool function. ;) i.e. Sliding down the stairs on one's belly. Nik was the winner, but that's only because he is twice as long as the other boys. LOL Jesse gave his nose a rug burn, but all in all it worked marvelously for releasing their pent up energy.
