The longer they have had any injury and depending on the severity, the longer it will take to correct. Chiropractic isn't magic, it will take time. Just like going to the gym, one time will not get anyone the body they want.....It takes time. A better example would be just like getting braces on your teeth, you don't get results in a week, it requires small adjustments over time and so does re-aligning your spine. The one thing your child has going for them is that they are still young, and will heal at the speed of light compared to adults....I miss being a kid!
Best wishes to a speeding recovery,
Yours in Health,
