I guess I would agree with Jack above. I suppose it depends on the ages and maturity level of the kids too. I taught all mine from a very young age about “enter object name here” since they were very young. Not only so they could be safe around my house but, so they could be safe if they ran into any of those objects anywhere else they went. I also didn’t want to make them afraid of those objects. I also didn’t want them thinking they were experts on the objects either. Fine line to dance on there.

Educate, educate, educate. Make sure the difference in reality is known between real life and the internet and gaming of things.
