Gymnastics: The Real Deal

Up to this point, our "gymnastics" experience has been open gym...you know, running amok all over the gym at our own discretion.  Last week, that all changed.  We started REAL gymnastics; having an actual coach and having to follow directions.
All things considered, I think we are doing well.  This is the first organized activity they have done, and they are loving it so far.  We are having a little issue with following the coach, but I blame their infantile attention spans.  They are good for the first 45 minutes of the 50 minute class, and then the last five minutes are like fun time at the insane asylum.  We have gone twice, and mommy is really hoping for them to settle into the routine at class number three.  I don't want to harp on them after class, because I want them to love it.  Then again, they have to listen and not run off whenever they get a whim either.  I'm trying to balance out the direction with the "good jobs!" and "wasn't that fun??"
