Vestibular Neuritis and Labyrinthitis. Vestibular neuritis and labyrinthitis are most commonly caused by infection with a germ (a viral infection) that affects the inner ear. These conditions typically cause vertigo, often with sickness (vomiting). Vertigo is the sensation that you or your surroundings are moving.
Child safety seat laws. All 50 states and the District of Columbia have child safety seat laws. Child safety seat laws require children to travel in approved child restraints or booster seats and some permit or require older children to use adult safety belts.
Once your child outgrows their car seat, they'll need to switch to an appropriately sized booster seat. It's recommended that your child remain in a booster seat until they're at least 57 inches, usually between the ages of 8 and 12.
