We setup a wreath after Sasuke went to bed last night, and this morning he saw it while it was still dark outside.  He pointed and said "this!  this!"  Sasuke doesn't have many words yet, but "this" is a fairly handy one to have picked up.  His first word was "Mama" at about 6 months.  Now he has "ねね" (sleep), "om nom" (eating sound), "this!" and occasionally "up!"
