We got a steal of a deal on a baby gate on craigslist. We put it up in between the living room and dining room. It's great because this way, Olsen can't wander into the dining room without intense supervision. The dining room is part of the entrance way, so a lot of debris ends up on the carpet that he liked to pick up and put in his mouth. In addition, Lucy likes to carry her food from the kitchen into the dining room carpet and not eat it all, much to Olsen's delight. I feel a little mean restricting the little guy, but I think it's for the best, since I don't vaccum everyday, like I probably should.
* there are still hazards in the living room, as you can see. We have a lot more baby proofing to do!
