Okay, you are a very good parent. In my opinion: -structure his life -make sure he keeps up at school (but no pressure and no home scholing, you're his father not his teacher. Consider pre-teaching by the teacher or teacher assisstent). - no attention to his speech. Talk slower yourself. If he's really getting out of breath by enthousiasm: "slow down sport, that's too much information for me to take in. My poor brain can't keep up!", in a friendly manner. - no speech therapy. Maybe later in life, 21+, if he chooses by himself. - confidence (the school thing. Sport? Judo?). Acceptence: he can be who he is. You appreciate him the way he is. All of these points reduce tension. I agree with the social thing, s.o. brought up. Let him interact, a lot. Teach him to make contact with people: eyecontact, staying relaxed (very important, comes with the confidence). Communication is about creating report together, not to speak fluent (don't mention that fluency bit to him, only when he asks about his fluency). I may edit this later on...Hope it helps. Well done dad.
