redditor1: "my son is 4 years old and cant speak or walk"

[kathisterima]

My cousin couldn't speak until he was 5 or so and has high-functioning autism, I think it was attributed to this? 

He had to do extensive therapy sessions to learn how to speak. 

Btw, now that he is like 16 you can understand he has a problem if you speak with him for longer than 10 seconds. 

So, I'm not sure how high functioning he is. Obviously, the spectrum is pretty large.
