When Mojo was a baby he slept in a crate in the hallway. I was afraid DH or I would roll over on him in our sleep and smother him!
When he was nine months old and fully housebroken, we started letting him sleep with us. He sleeps on a blanket at the foot of our bed, but will come up and cuddle with us if he sees one of us awake in the morning. He can easily go 12 - 14hours without a potty break now. He often goes to bed by 8:00 at night, without me, and will sleep till 10:00 the next morning.
