What is the general rule regarding an infant's weight by the end of the first year?

• A. An infant's weight typically doubles by the end of the first year.
• B. An infant's weight typically triples by the end of the first year.
• C. An infant's weight typically quadruples by the end of the first year.
• D. An infant's weight remains the same.

Answer: (B)

The weight pattern of a healthy term infant follows a rapid growth pace in the first year. After initial newborn weight loss in the first days, most babies regain and then accelerate their gain. By about 4 to 6 months, birth weight has typically doubled, and by about 12 months, it has typically tripled. This tripling reflects the high energy and protein needs for rapid development during the first year and how nutrition supports steady growth. So the general rule is that an infant’s weight typically triples by the end of the first year. Quadruplication would be unusually high for a healthy term infant, and remaining at the same weight would not align with the expected rapid growth in infancy.
