Final answer:
The American Academy of Pediatrics advises that breastfed infants should get 400 IU of Vitamin D daily to ensure proper health and development.
Step-by-step explanation:
The American Academy of Pediatrics recommends that breastfed infants receive a Vitamin D supplementation of 400 IU daily. Vitamin D is crucial for the absorption of calcium in the body, and while it can be synthesized by the action of sunlight on the skin, supplements may be necessary when adequate sun exposure is not possible. Dietary sources of Vitamin D include fatty fish like salmon, fortified milk, and breakfast cereals. However, the natural production or intake through foods may not always be sufficient, especially for breastfed infants who rely on breast milk as their primary source of nutrition. Hence, the recommended daily Vitamin D intake is important for their overall health and development.
