Whatever happened to teaching your kids not to let strangers talk to them or touch them? At some point moms have to stop hovering and empower their kids. My kids were out of the ladies locker room at age 5 or so, and jeez I was only in the room next door. Granted, they were total mayhem in the mens locker room with water fights and so on, but that's the exchange. A kid that is well indoctrinated in "don't talk to strangers" , especially a younger one, will come running back to you pretty quickly especially if you are right next door.

Most pervs want to get kids off in private, not assault them in a public dressing room.
