Feet discovery!

2 nights ago, Robbie grabbed his foot while I was trying to put him to sleep in his crib!  I was 'shushing' him and trying to calm him, and was watching his feet as he kicked his legs in the air (he had a lot of energy and was trying to get me to play), and when he grabbed his toes and hung on, I yelled "BUDDY!  You found your foot! Oh my goodness!"  After that, I decided it would just be cruel to make him lay in his crib, since I had added to his energy level with my excitement.  So downstairs we went for about an hour. 

Do you think he'll catch on, and always do new things in his crib at night just to stay up later?!
