I think most parents would only expose age related material to their children, but I don't think that's really the issue. I think the issue is WHAT the parents decide is suitable for their children. Something that you think may be okay, I might not be okay with, and vice versa. I mean, what does constitute suitable material for an 11 year old? I often underestimate my kids, and think they are not capable of handling something, and they always surprise me by being quite mature about it. I usually go by the adage, 'If they are old enough to ask, they are old enough to know the answer', and so far it's worked.
