By approximately what time are newborns expected to regain birth weight with adequate feeding?

• A. By 10-14 days.
• B. By 1 day.
• C. By 6 weeks.
• D. By 3 months.

Answer: (A)

Newborn weight follows a predictable pattern: after birth there is an expected initial weight loss from fluid shifts and adapting to feeding. With adequate feeding, most term babies regain their birth weight by about 10–14 days. By days 3–4 the weight loss is typically at its peak, and as feeding becomes established the weight increases until it returns to the birth weight within roughly two weeks. Regaining by 1 day is not realistic because the early weight loss hasn’t yet stopped, and waiting until 6 weeks or 3 months would indicate ongoing growth beyond the initial birth weight rather than a return to it.
