Patient's question:
A 9-month-old baby has recently been shaking their head and body a lot. Is this normal? Two days ago, they fell off a car seat and hit the back of their head. Is this related to that incident? Or is it related to calcium deficiency and iron deficiency anemia? The baby has bald spots at the back of their head.Doctor's answer:
First, go to the hospital to treat the external injuries that cause the child to shake their head. Generally, children should start taking calcium and vitamin D supplements from the age of three months. If they don't supplement, they will often be calcium-deficient most of the time. When children are calcium-deficient, they tend to sweat more, and the area where the back of their head touches the pillow may become hot and sweaty, causing the scalp to hurt. The child will often shake their head to relieve the pain in their scalp. Over time, this can lead to bald spots at the back of the head, causing the hair to thin in that area. What needs to be done now is to take the child to the hospital for a few tests to check for trace elements and determine the extent of their calcium deficiency. It is also necessary to give the child calcium and vitamin D supplements for a serious period of time.
