He's supposed to be tired

All we heard about 1st grade is the kids come home so tired after being in school all day.  We have yet to experience this.  If anything Tyler is bursting with energy.  I've been thankful that he has soccer on Mondays and Wednesdays to burn off some of that extra energy.  The only complaint I've herd is that his "bum" is sore at the end of the day.
