The baby’s hair is so dark, so dense, so beautiful! Wait, what’s going on at the back of the head, how come there’s a little “puddle” for no reason at all? A. Understanding the little “puddle”: Actually, this little “puddle” is called occipital baldness, and as the name implies, it is related to the pillow. It is a phenomenon where the occipital area of the baby, where the head is in contact with the pillow, has a circle of thinning hair or no hair. Most babies have pillow baldness at the back of the head, but some babies also have unilateral pillow baldness because they like to sleep on their sides. The causes of pillow baldness are: 1. Objective reasons: Babies spend most of their time lying in bed, and the place where their little heads come in contact with the pillow is prone to heat and sweat, resulting in an itchy scalp. If parents do not take care of it carefully, babies who do not express themselves will shake their heads from side to side to relieve the itchy symptoms, and this rubbing around will rub the hair off. In addition, if the pillow is too hard, it will also cause the phenomenon of pillow baldness. 2.Physiological reasons: Insufficient and unbalanced nutrition during pregnancy may also cause the baby’s pillow baldness, while thinning hair may also be a symptom of calcium deficiency in babies. 1, if for objective reasons, we can: (1) strengthen care: choose a breathable, moderate height, soft and moderate pillow for your baby, keep an eye on your baby’s pillow, find moisture, replace the pillow in time to ensure that your baby’s head is dry and cool. (2) adjust the temperature: pay attention to maintain the appropriate room temperature, the temperature is too high cause sweating, will make the baby feel very uncomfortable, while it is easy to cause the occurrence of other diseases such as colds.
