Team in a hitting slump!

[Twins Softball Dad]

I work with my girls every day and one of the twins was in a major slump. She battled out this weekend big time!! I have a righty and a lefty. My lefty is the go to hitter and the coach always moves her in the line up to help the team. Question is the rest of the team is in a MAJOR slump. I know what I tell my kids and I know what i would work on. Any drills you guys do to help the team. Problems are like most girls this age 12U Hands dropping, shoulder dropping. ETC It's frustrations to watch because I know ALL
these girls can hit!! Thanks
