Can it be so...?

La

My DS#2, (almost) 2y/o seems to already know how to play pretend. I noticed this a few months back but its become more obvious these days and I am not entirely sure if my theory is correct. My Ace (DS#1) never shown ANY signs of this whatsoever (but then again it's possible he may have ASD... Story for another time)

SOOOO my question is,

Could someone who has no prior knowledge of "make believe" can actually "play pretend" ???
