Additionally: the most important not is that you teach kids to face risks themselves. If you constantly hover around kids from the baby age onwards and jump in at the tiniest risk, what you teach them is that the world is a dangerous place that they are not equipped to deal with.
The cardinal mistake many inexperienced parents make is to think you can chose what your kid learns. So they will yell at their kid that it needs to be calm, something they fail at in this very moment. Kids care much more about how you live than what you say. You can tell your kid to respect nature, but what drives it home is if you show respect of nature without even mentioning it on a day to day basis.
Handling risk and uncertainty is one of those things. You can't tell your kid to be able to deal with uncertainty without fear, you will have to show to them (1) that you are also able to deal with it and (2) that you trust them to do it too. Sure they should ask their parents if something seems off or a bit too much to them, but there are so many parents who appear to trust their kid with next to nothing.
