My son is very athletic too.
And he knows that, himself.
From 2 years old he could dribble a ball, switching it to both hands, while walking or running at the same time.
He can throw like a pitcher.
He can kick, jump and do so many things, athletically, that is advanced for his age.
BUT.. ultimately, we go by HIS interests.
My son is now 4.5 years old.
He is not interested in taking soccer. He likes martial arts. He said so. He also likes music. That is his other, 'talent' and inherent, ability.
So, we go according to HIS interests.
We do not push him in one 'sport' or the other.
My son also likes Tennis. He is good at it. Already.
He told us, he LIKES tennis.
Being in "sports" should be something a child wants to do, as well.
Not just as a perfunctory thing, per the parents deciding.
The child should themselves, love and enjoy it.
It is not about 'competition', but having fun.
You as parents, do not have to be "jockeys" yourselves, nor into sports.
You can still, nurture your SON's, interests.
'Sports" constitutes a WIDE range of activities.
Myself as a child, I did not like 'team' sports. I liked individual sports. I ran track and cross country. I was good at that.
I knew, myself.
Let your son, KNOW himself too, and "his" interests.
There are many activities/sports.
It does not have to be huge organized sports like Football etc.
There are MANY Choices.
Personally, I do not like those kiddie ALL weekend sports things either. I really dislike it, because of the social obligations and social 'cliques' of the parents. But, if my son, 'wanted' to do say, soccer... then well, we'd try it. For him.
There are many choices, per 'sports.'
Even Golfing.
And, your son may not want to, do those 'sports' things either.
The point being, go by HIS... personal inclinations and interests...
The BOTTOM-line is... go by your son.
Just because he is "athletic"... will not mean, he WILL do all those sports things. He may have other ideas.
Nurture his 'whole' being.
Not just, the physical part.
But let your son try things... if he wants to.
Your son is so young. So who knows, what he will end up wanting to do.
As I said, even if my son is really athletic and it is his inherent ability.. HE... does not want to do those things. Not the soccer thing, nor the other sports. He told us.
He likes, marital arts and drums/guitar.
But we do let our kids try things.
all the best,
Susan
