As a past little league coach, I would advise you keep parents off the field! Remind them "It is not baseball, it is a tool for teaching baseball rules, motor skills, teamwork, and coordination, while getting childrens 21st century butts off the couch, while HAVING FUN so maybe they will want to graduate to baseball.
My best baseball player was my youngest daughter. She played fast pitch underhand softball. She was a rightie but the coach had her bunt leftie to put her a few steps closer to first base to try to outrun the throw or cause an error.
Best basketball player was my middle daughter. She was not tall (5ft) and getting discouraged, so I got her a "Muggsy" Bogues sports card. Bogues was the shortest player ever to play in the NBA, at 5' 3" Bogues - point guard for the Washington Bullets, Golden State Warriors, and the Toronto Raptors during his 14-season career in the National Basketball Association.
