Final answer:
Shaken baby syndrome primarily affects children ages 0 to 2.5 years and can cause brain swelling and retinal hemorrhage due to violent shaking.
Step-by-step explanation:
Shaken baby syndrome usually occurs in children ages 0 to 2.5 years. It is a severe form of physical abuse resulting from violently shaking an infant. This syndrome is associated with serious medical issues, such as brain swelling and retinal hemorrhage, which can occur due to the forceful shaking or impact to the child's head. Various stress factors such as economic hardships, unemployment, or the challenges of parenthood can contribute to this tragic situation. Unfortunately, an estimated 1,400 babies each year suffer injury or death from shaken baby syndrome, illustrating the critical importance of educating caregivers on the dangers of shaking infants.
