My 9-month-old daughter gets motion sickness, it's inevitable. Can she take Gravol at this age? I think it's not recommended.

No, Gravol is not recommended for children under 2 years old. There are no over-the-counter medications for motion sickness in babies, as it is not common in children under 2. You can try non-pharmacological methods to help your baby, such as ventilating the car well, avoiding feeding right before the trip, avoiding long and winding roads, and maintaining a steady driving speed.
