Dyspraxia is a difficult thing to understand. My son (now 22) is dyspraxic. Difficult to get help, misunderstood by education and social services. Clumsiness and coordination are obvious signs, but more problematic is social immaturity, different prioritisation and the fact that dyspraxics do not learn in a serial way like most others. There are local clubs that will help you as a parent and you and your son. My son has the same writing problem as yours at 22. He has just got his Honours degree from de Montfort university. So these things can be understood. It can be an interesting journey for you all
