Big boy Alex now gets his turn to face forward and see what is going on in the car.  When I first changed his seat we thought that he would be more excited (like Brooke was) about the change.  Then I remembered that his whole life he has had a friend and companion in the back seat so never was frustrated about not seeing us.  However, a few days later he was loving me checking my blind spot and looking at him then quickly back and now we can giggle at each other even when Brooke is not in the car.
