Dd is 5. Went to grandparents for a couple of nights but threw up at 2 am. Seemed ok the next day but was sick in the car home. She’s been home for a few days since but our first trip in car. She’s saying she feels dizzy and sick in car despite car sick tablets. She doesn’t usually have sickness in the car. Is the feeling psychological or does she need to see a Dr. Could she havelabyrinthitis or something?
