That's a great start!
As for attending the camp. Line Drives and Dives get the most attention. Be loud and vocal. If her team has a jersey color that stands out from the rest of the blues, reds, blacks wear it. All white "icy" looks good. Tell her to be first or 2nd in line when doing drills. If shagging in the OF, get crazy! She needs to be like a spider monkey trying to get anything and everything she can.
Just be different!!!
At the end of the camp they usually have a Question and Answer session. Make sure to ask questions, even if she knows the answer. Every camp it's always the same questions from the players. Once they break, the coaches will split off and lines will form so that the players can introduce themselves and chat for a bit.
After the camp, you need to grab your postcards that I recommended making a few months ago and write a little note thanking the coaches for their time. Make sure to mention something about the camp that will jar the coaches memory, and if there was something about the instruction that resonated with your DD.
Rinse and Repeat, on to the next camp!
Lots of great ideas! I'll get the postcards made up for next time. She did plan on dropping a thank you note in the mailbox right in town after the camp so it gets to them quickly. Should she do a follow up thank you email too?
