I don't really know what MG or HG development looks like, and I do know that if you've seen one PG developmental arc, you've seen one-- but this might be food for thought.
Howler Karma, you always bring such fascinating insight to the table. I love the above quote, seen it in several iterations before and it always hits home.
Environment always plays some part I believe, though little DS doesn't like to be taught or assessed in any way. The rare occasions I try to actually sit down and figure out if he knows something, he mostly just chucks the stuff I present and yells at me. So then we go back to playing pretend kitchen or listening to music instead, lol.
I suppose he'll get it when he gets it. And until then, we will enjoy (or at least, not worry about) the idiosyncrasies. :P
