My DD is 11 playing on a 12U team. We have been with the same team for almost 3 years (beginning of 10U to now). The team is mostly all 09 players but over the winter we picked up a few 08's. We are happy with our team and had no plans to leave. The 08 players have brought a lot to the team and we have had some success lately but nothing extraordinary. The coach is now saying that the team is moving up to 14U in August. His reasons being he doesn't want to lose the 08 players who have to move up and the 09s will be playing middle school ball in the spring anyway so it gets them more prepared. Our family has made the decision to not move up. We don't believe DD is ready for 14U and we want her to have her second year of 12U. I don't want to wait until the last minute to tell the coach we are not moving up but I also don't want to cause any friction while we finish out the spring/summer with the team. When is the best time to address this with the coach?
