What 10 years old looks like in my world

My son has turned 10. Physically, emotionally, spiritually he is not 10 but about 5 or 6. We are still working on helping him learn to read. Math is slow but we are about a 1st grade level.  We struggle every day with his attachment and acceptance of our role as his parents. Every day he tells us what new toy he wants. I tell him I could give you all the toys in the world and you would not be happy. You will only be happy when you allow yourself to trust mom and dad. ; and that is something that after 7 years he still can not do.
