Patient's question:
At six months old, my son is 68.5 cm tall and weighs 7.8 kg. He can roll over but cannot stand straight when supported on an adult's knee, nor can he jump. His left foot always taps and cannot be placed firmly and flatly. He also cannot sit independently for even a moment. What could be the reason?Additional question: At four and a half months old, my son had already sprouted two milk teeth.
Doctor's answer:
Hello: According to the situation you mentioned, it is recommended to take the child to the hospital for a trace element examination to see. The child's condition is very likely to be a symptom of calcium deficiency.
