When I was about two-three years old, my parents were concerned because I did not talk. I struggled in social situations and preferred being on my own with building blocks or trucks. I didn’t have a picture of myself, but here you can see my 3 boys doing essentially what I was doing – playing with things that have wheels. Anything with wheels or toys for building were the most appealing (LEGO Sets).
I learned much later that I was considered a "non-verbal" thinker. I did not do well in kindergarten or first grade and flunked second grade. I was given speech therapy and slowly caught up to others my age, but it really was not until high school that I felt comfortable reading and comprehending what I was reading. What I lacked in social skills, writing, or reading was offset by considerable skill in making stuff. I built pretty amazing castles and boats out of wood blocks and LEGOs. While upbringing specifics will obviously vary from Engineer to Engineer, I have yet to meet one who wasn't the master of LEGOS on the block. Now I know how its important to have nice toys, do if you are looking for 2 year old boy gifts or so choose the best and the most developing.
