Yep. With all of my kids, no locker rooms or team meetings out of sight. Always 2+ parents at events and they were not allowed out of sight and alone with a given adult for any reason. I have 4 grown kids and thankfully nothing that I'm aware of ever happened and they always knew they could talk to us if something did happen.
Any coach trying to say a parent can't be present is a red flag, absolutely. Either my wife or I was always at a given event for our kids until they started high school. We never viewed kids' practices and events as a form of babysitting. I know some people do that, but not our family.
