Which is NOT a sign of respiratory distress in a baby?

Excessive smiling is not a sign of respiratory distress in a baby. In situations of respiratory distress, infants typically exhibit behaviors that indicate difficulty in breathing or lack of adequate air supply. Struggling for breath, being unable to cry properly, and head bopping up and down are all physical manifestations that suggest a baby is experiencing respiratory challenges. These signs reflect the infant's physiological response as they try to compensate for inadequate oxygenation or airway obstruction. In contrast, excessive smiling is a normal social and emotional response and does not indicate any distress or breathing issues. Understanding these behaviors is important in assessing a baby's health and ensuring timely medical intervention when necessary.
