How can I get my baby to stop crying?

As I await the arrival of baby #1, I've been inundated with "advice" from friends and family.  Here's a link I was sent that features Dr. Harvey Karp - a pediatrician who claims to have some expertise in the area of calming colicky babies.  The basic gist is to help your baby feel like she did back in her happier days, ie in the womb.  It also showcases some inspiring hairstyles.

To anyone who has experience, any thoughts?
