You are the kind of parent that is deeply determined to scare off all sexual predators from your children. I have a therapy tip for you. We know that the majority of childhood sexual abuse happens at the hands of somebody who is known and trusted by that child's family, which means you can't rely on your gut or your intuition to know who is or isn't a pedophile in the vicinity of your child, but another.
About these people is that they do not want to get caught. Many of them are influential members of society and care a lot about looking good on the outside. So send a clear message to every single person who is ever going to have access and possible privacy with your child that you are thinking about and not afraid to address the topic of childhood sexual.
Just with my daycare providers, I always make a point to say, Hey, by the way, I just wanted you to know that my girls refer to their genitalia as their V because I teach them that so that they know the correct words because I know for a fact that that scares off sexual predators. If my daycare provider isn't a sexual predator, they don't care that I said that to them.
And if they are, they took very clear. That I am paying attention. And while we can't, with 100% certainty, guarantee that our children won't be harmed at some point in their journey, we can at least send a clear message to these predators that we're watching.
