Waking up happy

Luke usually wakes up crying....he has been this way for the past couple of months. It is very rare that he wakes up babbling. Last weekend (I'm really behind on posting) Sean and I were watching TV in the living room while Luke was napping when we heard a high pitched "dooogggggy" (the way he says doggy is so darn cute). He was really having a good time with whatever was occupying him. I peaked in and saw him sitting up "reading" his new book. He was on the zoo page pointing to the animals. Every animal is a doggy. Here he is in action. Like the crazy bed head?
