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.
Baby car seats are legally required in many countries, including the United States, to safely transport children up to the age of 2 or more years in cars and other vehicles. Other car seats, also known as booster seats, are required until the child is large enough to use an adult seat belt. This is usually, but not always, when the child is 1.45m (4 ft 9 in) tall.
