[@Buddha][@Superman] They already have notions of what most adults would have: Manners, gait, self-consciousness. One can't say they'll learn like newborns. But being exposed to a particular circumstance/fact will emerge the already existing, common knowledge they have on said things. The more they learn, the more this branches out and they associate ides with each other. Considering the amount shit they're learning at once here and make sense out of, it won't be too long before most of their behavior is engaged in a ;manner you'd expect from people their age.
