Newborns have more meat on the back of their necks, which is a normal physiological phenomenon and no need to worry too much, but it may also be caused by diseases (such as hemangiomas, etc.), and need to be treated by a doctor. 1. Normal physiological phenomenon: in the case of fat newborn babies, fat is easy to accumulate at the back of the neck, resulting in more meat at the back of the neck, which is a normal phenomenon, and generally does not need treatment, so don’t worry too much about it. 2. Caused by diseases: in the case of hemangioma, it may also cause newborns to have a lot of meat on the back of the neck, which can be treated by hormone, radiation, cryogenics, laser and other ways. It is important to note that if you are not sure about the flesh on the back of your newborn’s neck, you can choose to consult a doctor for evaluation and judgment.
