I found some CM quotes that might be helpful in encouraging your son to begin reading by himself:
“A child has not begun his education until he has acquired the habit of reading to himself, with interest and pleasure, books fully on a level with his intelligence.” “Once the habit of reading his lesson-books with delight is set up in a child, his education is–not complete–but ensured” (Vol. 1, p 229).
“It is a delight to older people to read aloud to children, but this should be only an occasional treat and indulgence, allowed before bedtime, for example” (Vol. 1, p 228).
What CM’s definition of an “older child” is, I have no idea–maybe 12 or 13 years old, or by 6th grade.
There is another passage out of Laying Down The Rails that I found about it being unnecessary for the mother to create more work for herself, but I can’t find it right now. (Guess I should’ve kept my habit of attention stronger while I was reading it!) Sonya would probably know exactly what I’m talking about and where to find it. She’s awesome like that!
