Tell me, I gave birth on April 18th. The baby has jaundice, we're still in the maternity ward, we're under the lamp, the baby is glowing and doesn't want to, it cries and screams immediately. They said at the maternity ward they won't prescribe anything if bilirubin doesn't go down! Has anyone had this experience? When did it drop? How many were like this?
