This is the full video describing the 5s's in much more detail if you're interested. It goes over each S, they explain the benefits, the whys, the hows, etc. Full credit goes out to Dr. Harvey Karp and here's a blog post describing the 5s's here. 

There are also little gems tucked away on that website like "There's a 'Golden Moment' for Putting Your Baby to Sleep" so it might be worthwhile to peruse the website and see what else you can find.
