You’ve probably taken your daughter out before and what happened? Probably nothing. It’s generally safe to go trick or treating, they’ll be other parents out with their kids who aren’t looking for trouble. I highly doubt any violence is going to occur to the parents or the kids trick or treating. The worst thing that will happen is she’ll knock on doors of grumpy people like me who don’t answer their door. No one is going to attack two adult women with all the other people around.
I probably have absolutely no business answering this thread as I’m not a parent and don’t have children. But I think having sz on top of being a parent can probably add maybe a little bit of a layer over protected-ness.
Like if I had kids and I brought them to a park to play one day and the “spies” or “men in black” started driving around us I know I would probably totally freak out.
But then again I think what you’re feeling is very natural as a young parent. Nobody wants their children to miss out, or be hurt in any way.
