K.P.
I would suggest a good chiropractor who treats children, to help minimize the future negative consequences of these daredevil acts. [Do get a recommendation, because there are some quacks out there; but a lot of chiropractors are great.] My sister fell off a horse when she was around 12-15 years old, and started getting a lot of ear infections, very bad, after that time. Regular doctors were no help, so finally she took her to the chiropractor she was seeing for her bad back, and with a few adjustments, her ears cleared up and she didn't have any more infections. (She's in her 30s now, and occasionally needs an extra trip to the chiro, if she strains her neck or feels an ear infection coming on; but he always clears it up.) That's just one example I cite to show that the neck and spinal column have far-reaching effects, and you can use chiropractic to help minimize it.
