just from the dad's response, it sounds like they know she's handsy. maybe not in a mean way but definitely in an inappropriate way. however, the dad should be the one enforcing that rule from home and perhaps he is not.
however, the mouthiness and disrespect is not ok in any class. if she gets away with it, your other students will have then learned it's ok to be that way with authority figures.
i would approach both the HC and parents with an initial, we love having your child in class and this is a rec class so we like to keep it lighthearted and fun but we expect her to be mindful of the rules and what her coaches ask her to do and any further behavior like this will end up with her being sat out or asked to leave the class that day.
i'm dealing with a child who is handsy and mouthy to other kids if he doesn't like their behavior. and this is at our church's VBS (last day tomorrow!). he went to kindergarten with my son but then went to a different town grade school after that. i've heard from the mom he's been labeled a trouble maker. now i can see why. and i see the exact behavior at VBS that she told me is happening at school. the mom dismisses it as in he gets frustrated easily, ect... in VBS it's a 3 hour camp for a week and i can deal and he can go off and sulk and i can put him in a different group to give some of the kids a break but in school, it's a set class and every day. his teachers must be pulling their hair out. i could not deal with him on a daily basis.
