being a part of the team

I have 2 sons.  Bob is 10 and typical.  My other son SJ is 9 and has PDD-NOS.  Bob plays basketball, soccer and baseball.  SJ used to play all of these sports, but he was having too much trouble fitting in with the team sports.  Technically, SJ could be on Bob's baseball team.  He is in the right age group, but due to the PDD he is emotionally a few years younger.  He can't always control his emotions, so when he gets out he tends to tantrum.  We chose to not put him on the team until he can try to control himself.  He still wants to be "involved", so I got him a matching team shirt and he wears it to the games.  Sometimes he is the scoreman and today he was the "equipment manager".  Today, Bob had a baseball tournament.  His team won all three games and SJ was as happy as any of the other kids on the team.  When we took a team photo, SJ was in there too.  Maybe he isn't a "real" team player, but I feel he is making great strides socially by fitting in on his own terms.
