Dr Karp demonstrates the 5 S technique
Real Dad doing the 5 S technique. Watch the baby's face and body relax.
Clint and I have found the "5 S" method by Dr. Karp to be AMAZING! It works wonders with crying infants. We wish we had known about this technique when we had Caleb! Dr. Karp explains why he believes this works with infants in the book and on the DVD. Disclaimer: We do not subscribe to Dr. Karps theories on evolution but the practical aspects of his method work.
I also take digestive enzymes which pass through the breastmilk and into the baby's gut. These help the baby break down the milk easier. Yogurt with live cultures (will say on the carton) are perfect for this. I also take Omnigest which is available through Walmart. Here is a study on Lactobacillus reuteri with some impressive results for colicky babies.
If the baby has gas, you can try Baby Fart Aerobics which gives techniques (movements such as bicycling the legs, massage) to help baby pass gas.
