Encourage your child to look in the direction they are traveling. For example, in a car they should look out the front windshield and not the side windows. Sitting in the middle of the back seat is helpful.
Be still. Children should already be strapped down in a car for safety reasons. If on an airplane or boat, they should find a place to sit or lay down quietly.
Eat a light snack like crackers. A small amount of food in the stomach is best as overeating and hunger pains can contribute to nausea. Bad odors (such as that of diesel fuel) can contribute to motion sickness.
Distract the child from their symptoms by listening to a song on the radio, singing or talking. Coloring or reading, however, can cause motion sickness and should be avoided.
Put a towel or curtain over the side window to block items that are moving past the window.
Place a cool cloth on the child's forehead and encourage him to close his eyes and lay his head back.
Contact your pediatrician about medicines that are available and appropriate for your child that help control motion sickness.
