My mother wouldn't put me in ballet or horseback riding lessons or brownies/girl scouts. I got swimming lessons so I wouldn't drown in the neighbor's pool and I was in 4H for a very short-lived time (maybe three meetings). I was 9 and she wouldn't let me do any of the workbook tasks that were marked for my age group, like making a grilled cheese sandwich. My parents are wealthy and I had computers, game systems and televisions in my room... so I have no idea why I wasn't allowed to do these other things. It definitely wasn't a money issue. Poor little rich girl, right?
My daughter has taken dance classes (including ballet), martial art classes, and she's always in soccer. My sons have had dance classes, musical instrument instruction, scouts, and sports, too. They want it, I try to make the money available to get it for them. We're definitely not wealthy LOL but it's worth the investment. It builds skills. Even if they try something for a month and decide they don't like it, they've had the experience to make that decision for themselves. My husband doesn't like when they decide they don't like something, but there are things they have stuck with that they do enjoy very much. Life at their age is about finding what's YOU and becoming really good at that while having a great time.
