I go back and forth about whether we should register for one. Our house isn't that large -- about 1,500 square feet, all one floor. The baby's room will be right across the hallway from ours. However, I'm thinking we might not be able to hear the baby if we're in the living room with the tv on, or when we're sleeping (lol like I'll ever sleep but you know what I mean).

I'd like to hear both sides, whether you registered for one (with a smaller house), or did not and your experience with that. Also, is an audio monitor enough, or did you do video?
