If the value is less than 15, then you do not have to do anything. If it is
higher than 15.0, then the nurse will come to your house/ apt to install a
device that sends out blue light. The baby has to be naked to be exposed to
this blue light. Once the value is less than 12 for 2 days, he/ she should
be fine.
I am not sure whether new born baby can 晒太阳.
