My son was born 6 weeks early with a severe case of torticollis. His spine was pulled to the left and his rib cage was shifted off center. We took him to a chiropractor starting at 5 weeks and had to do muscle therapy with him 5 times a day. He is 6 years old now and you would never know he was so crooked!!! Start with his pediatrician and have him seen by a chiropractor. They will advise you if he also needs physical therapy. Good Luck and don't worry too much. It doesn't sound as severe as my son was and he is great now.
