I'm just going from personal experience and observations.
If they are trying to learn, that's great.
Our millenial nephew has been living with us. We're trying to teach him to cook, but he has the attention span of a gnat.
The day I was going to teach him how to properly can venison, he wound up having to go somewhere...
My grandson is 4 as of November. He helps me cook all the time. Cookies, cake, apple pie in a sheet pan that is awesome, hamburgers, pancakes, french toast, a recipe we developed ourselves with hamburger, mushrooms onions and a bunch of other stuff. The list goes on. Teach them young!!
Gonna start my grandson at shooting practice real soon. Started my son at 4 years old and he is very good with about any guns now 36 years later. Plus we shoot bows and arrows as well. Silent and deadly.
My grandson and I are working on the garden plan as we speak. This youngin will know more by the time he is a teenager than most adult men know.
Oh gonna be learning that boy how to use tools as well. He will be helping me build our house from the foundation up very soon. We are setting up a small homestead/farm. Once we get there I am buying him a Kubota BX with a back hoe, a belly mower and a front end loader. Then give him a big pile of dirt to move around plus have him digging up stumps in the forest where we will be making way for a pasture.
Gonna restore and old car and maybe a truck as well. Hope to build a Baha Bug one day with him. Gonna restore an old tractor my dad bought when I was 4 as well. We got lots of plans and they will all make him a better man.
