THIS!!! DC was in Kindergarten and the first year of swim team. Another Kindergarten parent actually asked me what sport the child would be "specializing" in for college admission! The kids were SIX!
At the same time, DC wanted to try gymnastics (again, DC was too tall for the first class we tried at age 4). I called all the gyms looking for a BEGINNER class at a regular gym (the kids gyms set the equipment too low), the one I chose swore to me that all the kids were beginners and DC would fit right in. On the first day of class, three of her friends from school were there; they had all been taking gymnastics at that gym for FOUR years. The instructor would yell at DC for not knowing what to do. It was a disaster!
Why can't kids just try various things and HAVE FUN??? The world is way too competitive!
