A nurse is discussing growth with the parents of a 6-month-old infant who weighed 7 lbs at birth. Which statement best reflects the expected weight at this age?

A. "Your baby should weigh about 15 lbs by now" is correct. When discussing infant growth, nurses refer to standard pediatric growth milestones, which indicate that a healthy, full-term infant typically doubles their birth weight by 4–6 months and triples it by 12 months. Since this infant weighed 7 lbs at birth, the expected weight at 6 months would be approximately 14 lbs, making “about 15 lbs” an accurate and reassuring estimate. This reflects adequate nutrition and normal metabolic development. B. "Your baby should weigh about 25 lbs by now" is incorrect because this weight is significantly above the expected range for a 6-month-old. A 25-lb infant at this age would be unusual and could suggest measurement error or a rare growth disorder. C. "Your baby should weigh about 20 lbs by now" is incorrect because 20 lbs corresponds to an older infant, likely 12–15 months old, and is too high for a 6-month-old who weighed 7 lbs at birth. D. "Your baby should weigh about 10 lbs by now" is incorrect because 10 lbs is less than double the birth weight. If a 6-month-old weighed only 10 lbs, it could indicate growth delay, malnutrition, or other underlying health concerns, requiring further assessment.
