Doctor's answer:

From your description, the child's condition should be considered as neonatal bleeding caused by late-onset vitamin K deficiency. If the child is breastfed, it is likely due to the mother not eating green vegetables.
Advice: It is recommended to seek medical attention early and check platelet count, coagulation function, etc., to rule out any abnormalities. It is best to give the child an injection of vitamin K first to prevent the possibility of further intracranial bleeding.
