Early Neonate is a baby upto what age?

Correct option is B

The early neonatal period refers to the first 7 days (0–7 days) of a newborn's life.This timeframe is critical as the majority of neonatal deaths occur during this period.The World Health Organization (WHO) and the American Academy of Pediatrics (AAP) define the neonatal period as the first 28 days of life, subdivided into:​

• Early Neonatal Period: 0–7 days

• Late Neonatal Period: 8–28 days​

This classification aids in monitoring and improving neonatal health outcomes.​

Explanation of options:
(a) 0–3 days – This is too short and does not encompass the full early neonatal period.​

(b) 0–7 days – Correct answer.This is the standard definition of the early neonatal period.​

(c) 0–14 days – This extends beyond the early neonatal period into the late neonatal period.​

(d) 0–21 days – This includes both early and late neonatal periods but is not the standard definition for early neonate.​
