At what age does an infant's birth weight triple?

Choice A rationale:

Newborns typically need to be fed every 2 to 3 hours. This frequent feeding is essential because their small stomachs can only hold a limited amount of milk, and they have rapid growth and metabolism. Breast milk is easily digested, and infants require frequent nourishment to support their growth and development.

Choice B rationale:

Feeding a newborn every 8 to 10 hours would be far too infrequent and could lead to dehydration and malnutrition. Newborns need more frequent feedings due to their small stomach capacity and high metabolic rate.

Choice C rationale:

Feeding a newborn every 4 to 6 hours might be suitable for slightly older infants but would still be too infrequent for a newborn. Frequent breastfeeding helps establish a good milk supply and ensures the baby receives adequate nutrition.

Choice D rationale:

Waiting 6 to 8 hours between feedings would not meet the nutritional needs of a newborn. They require more frequent feedings to support healthy growth and development.

The correct answer is Choice A: Placing the infant downward into the crib.

Choice A rationale:

The parachute reflex, also known as the protective extension reflex, is demonstrated by holding the infant upright and then quickly tilting them downward (towards the crib or another surface). The infant should extend their arms forward as if to protect themselves from falling, demonstrating the reflex.

Choice B rationale:

Seating the infant in a stroller in an upright position does not involve the motion required to elicit the parachute reflex.

Choice C rationale:

Lifting the infant high in the air above her head does not demonstrate the parachute reflex. This action may cause startle or other reflexes but not the parachute reflex.

Choice D rationale:

Holding the infant in a football hold, cradling the head, does not position the infant in a way that would demonstrate the parachute reflex.
