When do infants typically regain their birth weight?

• A. By 3-5 days
• B. By 10-14 days
• C. By 1 month
• D. By 1 week

Answer: (B)

Infants typically regain their birth weight by 10-14 days after birth. After delivery, it is common for newborns to lose some weight in the first few days of life due to factors such as the loss of excess fluid, the transition to breastfeeding or formula feeding, and changes in metabolism. This initial weight loss ranges from 5% to 10% of their birth weight.

The recovery of birth weight typically occurs within the specified timeframe of 10-14 days because, by this time, most infants have adjusted to feeding and are starting to gain weight efficiently. Ensuring that the infant feeds adequately during this period is crucial for weight gain, as sufficient caloric intake helps to restore their weight and support healthy growth.

Weight recovery by this time frame is a critical marker in pediatric assessments, ensuring that the infant is feeding well and thriving. Understanding these developmental milestones assists healthcare providers in monitoring the health and well-being of newborns in the early postnatal period.
