How do i know if infant is having trouble breathing?

Signs that an infant may be having trouble breathing include rapid or shallow breathing, grunting sounds, flaring nostrils, or retractions (pulling in of the skin between the ribs or at the neck). You may also notice a bluish tint to the lips or face, increased fussiness, or difficulty feeding. If you observe any of these signs, it's important to seek medical attention immediately. Always err on the side of caution when it comes to an infant's breathing.
