Over the last month or so, Caleb has started to enhance his communications skills. One of the earliest things that he started doing was to wave "Bye Bye". We were in the living room playing with him one afternoon, when he just started to wave "Bye Bye" at us. It was hilarious coz we'll go "Bye Bye, Bye Bye Caleb" and wave at him and he would wave back at us.
Here's a pix of Caleb caught in the act of practising his wave...
