At 6 months, what is the expected weight of a baby relative to birth weight?

• A. Double birth weight
• B. Triple birth weight
• C. Equal to birth weight
• D. Half birth weight

Answer: (A)

Infant growth in the first year follows a predictable pattern: birth weight typically doubles by about six months and triples by about one year. So the expected weight at six months is roughly twice the birth weight. For example, a baby born at 3.5 kg would be around 7 kg at six months. Tripling occurs closer to 12 months, not at six months, while remaining at birth weight or weighing half of it would indicate slower or abnormal growth.
