What weight change after birth is expected in the first days for a newborn?

• A. 0-2% weight loss.
• B. 10-12% weight loss.
• C. 5-7% weight loss.
• D. No weight loss.

Answer: (C)

In the first days after birth, a newborn commonly loses about 5-7% of birth weight. This is due to natural fluid shifts, meconium, and the transition to milk, as the baby isn’t yet taking in large amounts of milk. Once breastfeeding establishes and feeding improves, weight gain begins and most babies regain their birth weight by about day 10–14. Weight loss within this 5-7% range is considered normal. Larger losses (around 10% or more) would raise concerns for dehydration or insufficient intake, while minimal or no loss is not typical during this early period.
