I think "COME" and "LEAVE IT" are big ones for us. We also say "SIT" alot. So I dont know. We also use "GO TO BED" alot. When I need to get something done or cook we will say "GO TO BED" and he will either go lay on the couch, under the computer desk or in our bed/his bed too

. and he will stay there until I tell him he may play now.
