I'm looking into buying a video monitor that I can watch from my phone. It makes me wonder if anyone would leave LO alone while they nap and take a quick trip to the store or something since you could watch LO on your phone while you are gone. Has anyone done this? I don't think I would go anywhere far, but it would make me more comfortable venturing further out into the yard (we have 5 acres) since currently our audio monitor doesn't reach very far.
