Doctor's answer:

Consider the possibility of vitamin D deficiency. I wonder if it has been supplemented. Generally, children should be actively supplemented with vitamin D after 14 days of birth. You can take children's Ekenxin to promote calcium absorption and prevent rickets. Add complementary foods in time. Eat some iron-containing, egg yolk, fruit puree, and vegetable puree.
