I teach the OODA loop in Martial Arts. Watching the pattern develop in my child was fascinating.

First object permanence, then two and three and eventually four dimensional tracking. Throwing is easy. Catching tool effort and developing these skills. I recall him reaching blindly at objects as he could recall their position in space, orient his body, and grab them without looking.

Having him catch Frisbees and racquetballs at 2 years gave me insight into what skill and observational development was required. At some point he was able to transition between projecting the path of a rolling object vs a thrown object.
