It is very hard to handle infants and illnesses, especially jaundice. I wish the baby good health in life.
she dismissed her fear saying it is nothing to worry about. she said exposure to early morning sun will correct it and the baby will be fine
This is very wrong. When there is a symptom, it is necessary that every test be performed on a patient to be safe. Disposing a parent or guardian fear isn't the bet way to go about it.
By this time the baby was about 5 days old if my memory serve me well.
This is too much suffering for an infant, the fact that the nurse first dismissed an earlier test could be the reason for an elongated stay at the hospital, putting an infant in a position of pain from health.
I am happy the child is fine, and you are doing great. Welcome back.
