We finally cleared out the dining room to make way for all the baby toys. (The picture above was from Thanksgiving '09 - yum! It is the only "before" picture I can find of our dining room.) Our house was being overrun and we didn't like that the first thing you saw when entering front door was a huge mess of baby things. So, our dining room furniture was moved into the garage and the baby toys were moved into the new playroom.
We bought a mesh gate that expands to block off the opening between the two rooms and we used a regular baby gate to block off the kitchen entrance. Now Ana and Javi have a totally baby-proofed area to crawl around in. They seem to love it!
