Oh and rapid returning, it helps if both parents tag team on the first few nights. It helps with staying firm, is good to have a break every 15 mins or so, and it is important to remember that they can need returning hundreds of times. They soon learn though. Three nights and there will be an improvement with most.
After the first initial few returns, try to gradually reduce the interaction - less talking, cuddling, kissing, eye contact etc.
Have a plan as to what to do if they wake later. I cannot afford for the whole house to be up, and with J it is usually pain that wakes him, so I bring him into bed as I need sleep. If you just have the one you can do RR once you have identified what has woken them. For example if they are ill then you wouldn't RR. If wet you would change bum first etc.
Not sure if you can get them on the internet, but we used to watch House of Tiny Tearaways when DD1 was small. We used to be so judgy of these parents with babies that didn't sleep in their own beds, wouldn't eat, etc. Clearly the Big Man was watching and sent J to teach me a lesson 
Anyway, I digress - the visual RR was very helpful. Much more so than reading in a book, and seeing the change in the families and the quick response made it something that stuck in my mind.
