By 7, children should already be practicing some personal disciplines in basic self care (teeth brushing) and managing their personal spaces.

10 years old is a good time to expand self care with additional hygiene (deodorant) ahead of adolescence, but it's also ideal to incorporate a few daily pushups or other calesthenics so this practice will be there during the years when their growth hormone levels will be the highest. And even 2 minutes of musical instrument practice daily can also be transformational.

A modest daily routine at a young age can be life changing.
