It's called Fashion, darling...

Joe has now progressed to a "Jolly Jumper" (a cross between a parachute harness and a bungee), and he absolutely loves it.  His coordination isn't great yet, and he will insist on curling his toes up when attempting to bounce, but this doesn't seem to dampen his enjoyment.  I'm not quite sure why, but his mother decided that he needed to wear a hat.  Why?  It's called Fashion, darling (apparently).
