Children can start learning to move with the soccer ball at their feet as soon as they can walk, or sooner.
It’s exactly what we do in the U.S. with baseball, basketball and to some extent, football.
Do you think most 10 year-old’s in the U.S. can throw a baseball to within inches of a target from distance because they suddenly gained coordination?
No, Dummy. It’s because they’ve been playing catch with stuff since before they could walk. It was the 8-9 years of repetition that built the coordination to do that.
Example of a sport in our culture:
Show a 4 year-old kid playing catch or 1v1 basketball with an adult. Some physician somewhere smiles and thinks, how great and healthy it is for that kid to bond with the adult and get some physical activity.
Example of a sport not in our culture:
Show the same 4 year-old playing 1v1 soccer takeaway with same adult. Same physician has concerned look and thinks, 4 is way too early for such sport-specific specialization, that could lead to injury, unrealistic expectations and burnout.
