I can confuse myself sometimes when the signals get too complex. This year we just went with armbands and everybody is much happier and confident!
Another newbie assistant 12U TB coach here so please forgive the ignorance! We just started our team a few months ago and have yet to win a game (0-9). Uggghhh..! However, we are working hard on mechanics and are seeing improvement each game so there is light at the end of the tunnel. Back to the question though, we are struggling with signs too and the girls are very confused most of the time but too embarassed to let anyone know. We saw a team with the armbands for the first time last weekend and I thought this was a great idea. How does it work? Do you just hold up a number to the batter/runner? Also, where do you get them?
