Same with my DD.Winter indoor workouts with parents working the hitting station.Had hitting coach walking around instructing the girls.Destroyed my DD swing also by having 5-10 different parents "instructing" her on how to "fix" her swing that I thought was fine.Took half of the season and the help of this forum to get her swing back to where it was in the fall.Becareful with who is instructing your DD or DS always keep learning and studying.
