A nurse is collecting data from an infant at a well-child visit.The nurse should expect the infant to double his birth weight by which of the following ages?

Choice A rationaleInfants typically do not double their birth weight by 2-3 months. This milestone is more commonly reached slightly later in infancy.Choice B rationaleBy 5-6 months, many infants double their birth weight, indicating healthy growth and development. This timeline aligns with common pediatric growth patterns.Choice C rationaleWhile growth continues at a steady pace, most infants have already doubled their birth weight before reaching 9 months. This age generally marks further physical and developmental milestones.Choice D rationaleBy 12 months, infants have typically more than doubled their birth weight. This age is associated with continued growth, development, and new milestones.
