After ten months of pregnancy, she gives birth. Many mothers soon find that it seems to be safer to carry it in the belly. Because the arrival of a baby means endless emergencies. Mothers have to worry about the baby\’s eating, drinking, diarrhea and sleeping. This kind of worry can be said to be from head to toe, from the inside out. Today we are going to talk about the \”hair\” that worries mothers. Many mothers, especially those who share photos and videos of their babies in the group, look at the thick black hair of other babies and can\’t help but be concerned about the few sparse hairs on their own babies\’ heads. Especially worrying. They are worried about whether their children are deficient in nutrients. Among them, the most suspected concern is that their children are deficient in calcium. Especially when children have bald pillows when they are young, most parents think it is due to calcium deficiency. In fact, the amount of hair in a person is closely related to heredity. Therefore, there are great differences between individuals. The problem of hair thinning in most babies has nothing to do with disease. As the baby grows older, his hair will gradually become thicker. The editor\’s second child\’s hair is now very thin, but because there is a precedent for Dabao, we don\’t worry too much. The eldest and second child of the editor\’s family actually have a bit of hair inherited from their father, and the hair on their forehead is relatively sparse. However, Dabao now has less hair than children with more hair, but it is much more than when she was a child. Below are the comparison photos of the editor’s Dabao’s hair before and after. Only by comparing can you know! Dabao is five months old and Dabao is four years old. Of course, if the hair is sparse, some diseases, such as rickets, must be ruled out first. Thinning hair is one of the typical symptoms of rickets and needs to be watched out for. But this does not mean that having less hair means rickets. In addition to sparse hair, rickets also requires comprehensive observation of the baby\’s other conditions: excessively large fontanels or delayed fontanelle closure, easy awakening during sleep, irritability, etc. If you are not sure, take your baby to see a doctor promptly for confirmation. If the baby can supplement 400 international units of vitamin D every day two weeks after birth, and can regularly add complementary foods to the baby after the complementary food introduction period, the baby will generally not suffer from calcium deficiency. Mothers should try not to supplement milk, calcium, etc. to their children by themselves. Additional supplements can sometimes do more harm than good. In daily life, caregivers can often take their babies to bask in the sun when the weather is good. In normal times, mothers can also give their babies head massages from time to time to promote local blood circulation, which is very helpful in promoting hair growth.
