This is obviously a real dilemma between empowering kids and helping them learn to make decisions, and simply being their parent. This is definitely a situation by situation type thing, ... dependent on age, level of play, family dynamics, travel commitment, finances, and other stakes.
I literally "forced" dd to play softball when she was little, game was WAY "too slow" for her as a basketball & sokker player. She really didn't like it, but she had talent. She liked it a LOT more once she got on a really good team, that was highly competitive, and demanded that every player function on every play. I steered her that way, heck she was afraid to even get out of the car at 11u try outs till "Silver7" came over and made friends with an offer to throw, with her great smile ...
We made decisions for her at the early ages, with her agreement (begrudging at times). As time has passed (15u now), she progressively makes most of her own decisions now, with our parental input as the "voice of reason"
She is her own young lady now, and is making more & more of her own decisions. Softball has been a good long term exercise in learning decision making processes. BTW, she is VERY glad that I would not let her quit softball, which would have been her choice, back then. She loves her team, and playing.
