My son is now 5 also (6 in June). We first started him out bowling in a kids bumper league (at Cassat Batt Bowl). He also plays Soccer at Westside Soccer Club. They have a website (www.westsidesoccer.org). Also, you can check into the YMCA. I know that the Dye-Clay branch has many youth sports. They also have a website (www.ymcaffc.org)
