My thoughts are with you, I know how it breaks your heart to hear a baby cry for even one minute. Those first weeks can be so trying. I totally agree with the previous poster to address needs, providing there is no medical issue, babies mainly need to be held and nursed to prevent crying,
In western cultures 2-3 hours a day is 'common' for newborns to cry according to studies, however babies that are carried or worn in a carrier or sling, cry 43% less. Babies tend to cry out of feelings of abandonment or hunger. Excessive crying, as associated with colic, is often unheard of in cultures where mother is rarely separated from infant.
Le Leche League mothers, who are encouraged to feed babies on demand and watch for prefeeding cues instead of crying, tend to have babies that cry less than most western cultures. Babies that are responded to promptly within the first six months of life tend to cry less in the second six months.
All of this I learned while reading the book Vital Touch. You can scroll through the book's chapter, Crying Myth, in the following link (scroll up to page 195 to begin):http://tinyurl.com/2cld2up
From my own experience, I found that my son needed to not only be in arms or carrier most of the time, but also sleeping next to me in bed versus a crib next to the bed. Even though I was able to reach right into his co-sleeper crib he really needed to be right next to my body in order to feel secure. It worked so beautifully once he began sleeping in our bed. He finally felt secure and safe.
By the way, if you should here the erroneous info that crying strengthens the lungs, it's not so. Within the first two days lungs are fully expanded. That was an old myth at the turn of the century that medicine has now proven false. Only saying this as I had this falsehood spoken to me when my son was a newborn. I was hyper responsive and someone told me to calm down 'they need to cry'. I doubted that nature and biology would not have made it normal to let a newborn cry and use up energy, calories, and be stressed like that, but regardless someone said it to me (not sure if you've heard it yet).
Best wishes and congratulations on your new baby. You'll be a great mom. I cannot tell you how much mothering.com has helped me. That and two books, The Vital Touch and The Baby Bond.
