Motion sickness is when your child gets dizzy and nauseated while riding in the car, a boat, train, airplane, or on amusement park rides. Motion sickness is common, especially in young children. The problem is due to an inherited sensitivity of the equilibrium center located in the semicircular canals (inner ear). It is not related to emotional problems.
Have your child lie down and keep a vomiting pan handy. Give him only sips of clear fluids until his stomach settles down. If your child goes to sleep, let him sleep. Usually, children don't vomit more than once, and all symptoms disappear in about 4 hours.
The best treatment for motion sickness is prevention. Buy some nonprescription Dramamine at your drugstore. Dramamine comes in 50-mg tablets and a 15-mg/teaspoon liquid. The dosage is 1 teaspoon of liquid Dramamine for children 2 to 6 years old, 1 tablet for children 6 to 12 years old, and 2 tablets for children over 12 years. Give the Dramamine 1 hour before traveling or going to an amusement park. The tablets give 6 hours of protection and are very helpful.
Also, consider buying an acupressure wristband. This may help your child during car, plane, or boat trips.
