I only have one child. And the entire living room is currently a battle scene of Legos, MegaBloks, antique Star Wars toys, army men, and miscellaneous other items. If I move anything, I get in trouble. And DH plays with him, so it's all good. I didn't even vacuum before the grandparents came over for his birthday, because we would have had to deconstruct the battle scene. And it took too long to build to even go there. I only ever go in there on the weekends anyway. With a book, on my corner of the couch.
