In a newborn, regain of birth weight is expected by approximately how many weeks?

• A. 1 week
• B. 2 weeks
• C. 3 weeks
• D. 4 weeks

Answer: (B)

Newborns typically undergo some weight loss in the first few days after birth due to fluid loss and meconium passage. With adequate feeding, this weight is usually regained, and the infant returns to the birth weight by about 10–14 days, roughly two weeks. So the best answer is around two weeks. If weight gain is slower and the baby hasn’t regained birth weight by about two weeks, it prompts evaluation of feeding adequacy and potential health issues.
