I caught Bo watching the dryer finish a cycle one morning. Then, he caught me taking a picture of him so he came chasing after me in his walker which is the close up you see here. He is certainly becoming aware of the world around him. He investigates the sounds he hears in the background . The walker has made him so mobile through out the house that he is able to explore and learn on his own. 
On his adventures in the walker, Bo will sometimes find himself in a dark room with nobody around. This triggers immediate panic and he will begin to cry. Mommy or Daddy will always come to his rescue and the roaming continues after the tears are wiped away.
