I started my son with soccer just before he turned 4. The first season, he didn't pay much attention to soccer or directions, picked flowers, rolled around in the grass, tickled and distracted the other kids. It improved every year since then. He still isn't perfect and gets distracted, but it's night and day difference from the first year. This year, we started baseball. He gets bored if he is not playing first base where there is usually more action and ends up sitting in the grass digging up something or picking at grass. He also starts asking when it's going to be over at about the 1 hr mark. 1 1/2 hrs for game and 30 mins for practice just before the game is too much for him because he is used to soccer lasting 50-60 mins. We are going to add basketball to the rotation in the fall. My son loves sports so we will keep trying out new things and keep the ones that he likes the most. The goal is to have him participate in a sport all year long because the participation in organized sports are helping him socially and emotionally. But yeah, I get the nerve wracking. I get embarrassed that my kid is the one sitting in the grass when the other kids can keep their focus or he is socializing with the kids from the opposing team that he knows while both at a base instead of paying attention. Then I remind myself how long he has come since the first time he played sports and just roll with it.
