Talk to him a lot and ask questions with follow up why, where, when, etc. Also the more you expose him to, the more he learns, take him yo see a real train, a real truck, etc and explain what it is. Most importantly show love and give them fun. I love playing sports with my boys or just wrestling around. Every sat and sun we go for a 1 - 2 hr trip on a red wagon in the park, they throw sticks, rocks, etc. KISS
