However you put it, the parent (if around) is the closest and most frequent point of contact for any child. A parent doing an OK job would be a reliable resource whom the child can approach with any questions arising from weird "discoveries" online or even in the community. A parent doing a splendid job would proactively educate their child about the world and it's messiness so said child is equipped to confidently handle much of what pops up. A child should be able to recognize and avoid predation when they encounter it.
