> I just wanted to mention that I was raised with calculated risk taking valued over safety

Just to clarify: we're really not talking about absolute safety, our five-year old seems to be routinely covered in bruises incurrent from falling while climbing on things. Last month she had a couple of slightly loose teeth due to landing on her face while falling from (adult) shoulder height at a playground :eek:

I'm not sure the kids can process "be safe enough" but that's the intention in the "rule"...
