These are great skills to learn as early as possible! Here in Norway, kids are in kindergarden "barnehage" from ages 1-5 approximately. They spend a ton of time outdoors and many even get to learn these kinds of skills. One of my colleagues actually has his son in a barnehage that is completely outdoors.
It's a shame this isn't more common in the US, but if there is somebody to start a strend, I believe it's you @papa-pepper!
