Question
A five-and-a-half-month-old baby makes a whistling sound like a mobile phone’s electrical hum or a faint police siren when the head is approached. This sound is continuous and can be heard at any time. The baby sleeps well, eats normally, and does not have any special crying. All checks at birth were normal, and the baby has never been sick. Experts, what could be the cause of this sound?
Answer
The newborn’s red blood vessels may be due to a thin stratum corneum, with capillaries distributed too superficially, causing red blood vessels or flush on the face when exposed to cold and hot stimuli or emotional excitement. No treatment is currently needed.
