Edit: chiropractic school is as long as medical school, they just spend more time practicing then interning. And you need a bachelors degree first. I trust a chiropractor with my spine more than an MD, because MDs aren't trained in chiropractic and spend more time learning about other things, where chiros learn about just what they practice. They ARE doctors! Medical mistakes involving drugs, surgeries, etc are far more likely to cause harm than a gentle adjustment.
The tool is called an activator. Sometimes they use it, other times just gentle pressure with their hands/fingers. All of the chiros I know work on kids, but it does help to find one who does it regularly. You can look at the icpa website, or just ask around to see if they do it. I've found that docs who are also parents themselves are most comfortable and understanding.
My babies and I have been adjusted our whole lives. Less illness, faster recoveries, better health and wellness all around. And it starts early! The birth process is pretty traumatic, and growing and adjusting to life is not easy either. Add in head bumps, falling, and other childhood events, why not take them? Keeps ahead of the headaches and pains adults can experience later after letting all of these events take their toll on our bodies and nervous systems. Good for you!
