To be honest he sounds a little young. if he were my son i would keep the activies coming, keep making them fun and let him enjoy his early years without any pressure. it comes to them soon enough with school and the like. also once he gets to school, if there is a potential there, i'm sure the school will spot it. he sounds like a bundle of fun and thats surely the best way to be!! Might be worth having a look at the sports centre at Lilleshal once he gets a little older?? Hope this helps.
