When living without sleep becomes a way of life you get used to. When you can get up 5 times in the middle of the night and learn how to go right back to sleep. When you can run the gauntlet of children's toys in the middle of the living room without twisting an ankle. And, when you can start to imagine your wife as the hot au pair sleeping next to you in the bed at night...that's when you realize it's official. The tiny little baby you brought home 7 months ago is now officially your legally adopted son. Life is good.
