Hi A.,
First of all, going to the chiropractor should be perfectly safe, but ask before you make the appointment if the doctor has experience in treating infants. Chiropractic care can help a multitude of problems, but our medical doctors and insurance companies want us to view them with suspicion because they take a natural, drug free way of treatment, and that just doesn't cater to the medical community who want us to stay on prescription drugs and have expensive tests so that they will not lose money. And I am a nursing student, so I am one of the medical community.
Secondly, chiropractic care does not have to be ongoing. Sometimes an adjustment can be made and it will solve the problem. But in other cases, like mine, the back gets out of alignment just through the process of living, and further visits are needed. I know that when I was under the care of a Chiropractor last year it really helped me, but now I have been suffering for several months because our insurance company only pays for 12 visits a year, and when the spine is really messed up, like mine, those visits are used up quickly. But chiropractic care is not a necessity, it only makes me feel much better. So I continue not to go because of my schedule and because we have a super tight budget.
I recommend that you take your son to the chiropractor if you can find one that has experience with infants. At least give it a try. And although he may have a return of symptoms when he is older, you can decide then whether you want to take him back or not.
Chiropractic care should be an on-going option, just like regular medical visits are. It's just that for some reason, chiropractors have been stigmatized. If you yourself were considering chiropractic care you would seriously consider before you went. But if you made an appointment for a yearly physical with your gynecologist, you wouldn't think twice about it.
