What should I do if my baby loses a lot of hair?

Question 1: My baby is 45 days old. His hair was fine for a period of time when he was just born. However, he started to lose hair after taking a bath at the full moon. He also lost hair even if he didn’t wash his hair, even on his hat. May I ask what\’s going on? Do you need calcium supplement? Dr. Luo Zhen’s answer: A child’s hair after birth is all lanugo. The growth period of lanugo is short and it will gradually fall out over time. Its color and thickness do not represent future hair. A baby\’s hair follicles will begin to develop rapidly around the age of 1, and generally the hair will be fully grown by the age of 2. The color and thickness of hair are closely related to heredity. Parents do not need to be concerned. Most cases have nothing to do with the lack of trace elements. In addition, trace element tests are inaccurate and cannot be used as a basis for diagnosis and treatment. There is no need to supplement calcium, just supplement with vitamin D every day. Question 2: My baby is two years and five months old. He likes to eat snacks but not staple food. His bowel movements are normal. What is going on? Dr. Cui Lixia answered: This is a matter of habit. As a parent, you must intervene and do not allow your children to eat snacks. If you don\’t eat, you have to wait until the next meal. You cry in the middle and have nothing to eat. It usually doesn\’t take more than a week to get rid of this bad habit. Question 3: What items are included in the physical examination when the baby is 42 days old? Dr. Pan Guilan answered: Generally, length, weight, heart, and lung auscultation will be tested. The specific results will be determined by the local hospital.
