Hi there! I have not needled someone this young, but know colleagues who have successfully. If they are willing and able to sit still for you, age (in and of itself) is not a contraindication. Biggest thing is obviously parental consent along with the child understanding what is happening. The neck and upper trap are obviously precarious areas so be sure to take that into account of your decisions and of course…only do techniques you are trained in. Hope that helps!
