I see. Thank you so much for sharing, Blackcat! This is going to be a long road of learning for me. We are not really doing academic stuff at home. His preschool is play based and works on SEL a lot, but not very academic either. If he is indeed extremely bright like DH, then this will explain why he doesn't read yet. They did work on rhyming at school at around age 3-4, and DS did great, and then they worked on writing the name, etc. But not much nor extensive work for teaching reading. But he has really great SEL progress, and he is also great at gross and fine motor skills and sensory - the school works on all these which I think is a great foundation, I agree with their priorities, esp as DS used to have sensory over excitabilities.
