H@rv.e.y-b.aby, Boy genius?

Holy buckets!!! This boy just pulled a fast one on us. Daddy and I were sitting next to each other on the couch. I was holding baby, and he had his face buried in my shoulder. He looked up at Daddy and then buried his face again. HE kept doing it and smiling when he looked up, turnign it into a game of peek-a-boo. Daddy started saying "boo" at him when he would look up. Baby thought it was such great fun. And then....then...Baby started saying BOO to Daddy!!! He did it about 5 times. We were all laughing so hard. Who would have thought a game of peek-a-boo could be so much fun?
