I am touched to see what these minors are doing. For a child who is only 5 years old, holding an ax and removing stones from the garden and then collecting them somewhere is very hard work. But I saw that he was happy to do it.
You're right, a 5 year old doing it all is a blessing. It will be a valuable lesson for the future and his life when he grows up. How not, out there children their age have been held hostage by addiction to gadgets or smartphones whose use is not appropriate for their age.
These two children are very lucky to get an education from their good parents.
