When is a child fit to be enrolled into a drawing class?

I think when you can see that your child willingly hold colours and has a good grip, you can enrol him in drawing classes. You can encourage him in colouring and drawing at home and let him draw him whatever he does. And once he starts colouring, initially praise him the way he does and ;after him you can guide him how to colour inside the outer lines and other things. When the kid is 5-year-old, he is old enough to understand instructions. And before that you can encourage him to draw and colour at home. You can also sit and draw your own thing along with him. When kids have company, they love to do the activity.
