What is a baby to do?  Things move pretty slowly in baby world, but she keeps her self busy in the typical newborn ways.  Her favorite activity is smiling.  Of course it is self-perpetuating… her smile makes us smile, makes her smile, etc.  Next up, is hand/mouth exploration.            She can easily bring her hands to her mouth now and enjoys rubbing her fists and fingers in her mouth.  Hands usually do the exploring, but in this situation, it is the tongue that explores the hands.  Talking, hair pulling, etc.
