But that very precosity of intellectual development (as opposed to precocious knowledge/understanding, which I'm pretty sure isn't the case) can produce an entirely different trajectory, I'd say-- so no, it's definitely not like a bullet train on the same tracks as the freight locomotives. It's fundamentally different to have experienced "I don't want to use that object to pull myself up to a standing position, because-- well, THEN WHAT? I'd be stuck. I should consider how to move about better. Or at least how to sit back safely on the floor. I'll think on that."
Oh thankyou! THIS is my children. None of whom are particularly academically precocious. But my EG/PG child in particularly, was observably different in the way you are describing from birth. The number of "wow" / "only she would do that" comments she had as a baby were constant.
