Cause of new born baby changing colour
You're referring to the phenomenon where newborn babies often appear to change color in the first few days of life!
This is a normal and harmless process, and it's caused by several factors. Here are some reasons why newborn babies may appear to change color:
- Vasopressin: Newborn babies have a high concentration of vasopressin, a hormone that helps regulate blood pressure. Vasopressin causes blood vessels to constrict, which can make the skin appear bluer or more pale.
- Blood circulation: Newborn babies have a different blood circulation pattern than adults. Their blood vessels are more superficial, which can make their skin appear more pale or blue.
- Mucus and vernix caseosa: Newborn babies are covered in a thick layer of vernix caseosa, a waxy substance that protects their skin from the womb. This substance can give their skin a yellowish or greenish tint. Additionally, meconium, the first stool, can also stain the skin, making it appear darker.
- Jaundice: Newborn babies often develop jaundice, a condition where bilirubin, a yellow pigment, builds up in the blood. This can cause the skin to appear yellow or orange.
- Skin mottling: Newborn babies may have skin mottling, which is a normal variation in skin color. This can appear as patches of red, blue, or yellow on the skin.
- Environmental factors: Exposure to cold temperatures, stress, or changes in humidity can cause newborn babies to appear more pale or blue.
As the baby grows and adjusts to the outside world, these factors tend to resolve, and their skin color may appear more even and healthy. If you have concerns about your baby's skin color or overall health, it's always best to consult with your pediatrician.
