When I was pregnant, I insisted upon getting a video monitor since Olivia's room is upstairs and ours is down. When I first put her in her room, at about 2 months old, I couldn't sleep because I was always staring at her on the monitor. This is not a problem anymore!
I came home the other night after a wedding rehearsal, and Matt said Olivia had been sleeping like this for hours. Note that she is at the top of her crib, laying the "wrong" way. It was just about the cutest thing, so I had to restrain myself from going in there and hugging her!
