Yes, you do see Crosby doing a jig in front of the music on the television. He has become quite a dancer and almost rivals his brother in the "fancy moves" department. (see the old posting of Quinn on Halloween...) Crosby is very good at spinning circles and stomping his feet- all he needs now is a fiddle. :)
Crosby also has a fun time tearing it up at the "big kids gym" with his older brother and is learning how to keep up pretty well.
