Keep your DD's batting stats. Know when she is hitting good. Know when she is off. I always kept her stats myself. Sure I may have been accused of being biased in my score-keeping, but I always knew where she stood relative to other players.
If you hit in the top half of the team, they will move you around and find a position. Hit in the bottom half of the team, and your DD is always on the bubble.
It is when you get to the cream of the crop teams, A-level, gold teams, that being a great hitter may not be enough. Other factors take over, as most all the players can then hit at a high level.
Make sure your DD keeps her weight down. Heavy players at 12U, only get heavier, and wash out. Push yourself away from the dinner table, something rarely mentioned, and has very little to do with effort, or commitment to a coach. This is something that must be done at home.
Parents don't realize how important weight is. Players spend thousands of hours practicing, playing, and miss the core problem area of being too heavy.
We have the opposite problem - if anything we are always told shes so small, not strong enough, her hands dont fit the ball well yet, etc. maybe moving up to 14u she was just small... But not much i can do about that one! Lol
