• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Infants grow very quickly in the first year. After an initial, small weight loss after birth, most babies regain their birth weight within the first two weeks and then continue gaining steadily. By about one year, many weigh about three times what they weighed at birth. This rapid growth happens because their energy needs are high, and breast milk or formula provides the calories and nutrients needed for both body mass and organ development. While the exact timing can vary from baby to baby, the pattern of doubling birth weight by around 4–6 months and tripling by 12 months is a common and expected trajectory.
