My daughter is 8 but will turn 9 during softball season. Her and a few others have the option of staying in 8U or moving up with most of the other girls from their previous team. My question is, would they benefit more by staying back in 8U to master more of the basics they learned last year, build confidence, leadership, etc... or move up with their team, so they aren’t behind next year when the other girls have a year of kid pitch under their belt?
