the patches should be your last resort, only if your son suffers from severe motion sickness when he rides in the car or flies on an airplane. If his peditrican says no to the patch, i would go with that recommendation. If he suffers from mild motion sickness when flying or riding i would suggest over the counter product like Bonine or Dramamine. The "natural" method which works great for me is ginger- ginger candy, ginger cookies, gingerale(must be made from real ginger). The ships are very stable so unless he is prone to motion sickness chances are that he won't even need anything.
