I. Parental responsibilities
The four-month-old child is still very young, his body is not fully developed, and his bones are still fragile. They can't stand massage or blind treatment. Parents should take their children to a big hospital. The community hospital is too small and the medical equipment is not perfect. I think parents have the responsibility.
Second, the responsibility of community doctors.
I think community doctors are also responsible. A four-month-old baby girl is too young to stand the wrong treatment. If the doctor is not sure, don't treat it at will. The baby still can't stand the toss, and the doctor has the responsibility.
