My son (7 yrs in 2 weeks) has starting to complain that his "stomach feels shaky" when we are in the car. Today we drive in NYC to see eye dr which is 45 min. He did not complain but on the way home he said he stomach was starting to feel shaky. He has said this on some other occasions as well. We were planning to drive to WDW this summer but now I am worried. Can I try over the counter bonine? Any other suggestions? How will I know if he can handle the long ride? Does the feeling usually go away after a while?
