N.S.
I have an AMAZING chiropractor that has helped my whole family (children included) with numerous things in the past. Unfortunately, he is in Sugarhouse, but I think he's well worth the drive. He is really good with kids, my daughter loves him. I think he has another doctor in Farmington that practices his same type of chiropractic (kinesiology), but I have never been to him. The guy in Sugarhouse is Dr. Kevin Morgan, ###-###-####. They could probably refer you somewhere up north as well. (And I know for a fact that he does work with cholic-y babies.)
Good luck!
