What is the NPO fasting time for Breast Milk?

• A. Up to 8 hours
• B. Up to 6 hours
• C. Up to 4 hours
• D. Up to 2 hours

Answer: (C)

Gastric emptying rates and aspiration risk drive NPO times. For healthy infants, breast milk is digested and cleared from the stomach faster than formula but slower than clear liquids, so the recommended fasting window before anesthesia is up to 4 hours. This balances reducing aspiration risk with not unnecessarily prolonging hunger or dehydration in a young child. In contrast, clear liquids are allowed up to 2 hours, formula typically requires about 6 hours, and solid foods 6–8 hours. Therefore, the best choice is up to 4 hours.
