I don't think we know.

A lot of kids do not bloom until well after their toddler years. And a lot of early lights slide back in relation to their peers. Some have an event that pushes them into excellence.

I think you need a model of how the mind develops that will generate predictions which are testable.

Given the influence of internal biology and puberty, diet, disease, parents, culture, peers, etc, its a difficult target to measure or even model.
