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.
Children up to two years old (24 months), are not required to have their own seat as these children may sit on an adult's lap. Only one lap child is allowed per adult. If one adult is traveling with more than one infant under two years of age, a seat will have to be purchased for the second infant. You can also choose to purchase a seat for your infant as long as you have the proper child restraint device.
