My LO had jaundice. It went from 9 to 14. Stayed at 14 for a few days then went to 11. Now he isn't yellow anymore so our doctor stopped testing him.
We had to feed him every 3 hours, and he had to eat at least 2 ounces. She told us the more he ate and POOPED then the better it would get.
He is almost two weeks old, but the jaundice has been almost gone for about 3-4 days now.
If I were you I would demand the light if her levels are still high. To me, 5 weeks seems like a really long time. I cannot believe they haven't done anything about it yet.
My doctor told us, when his levels were 14, that if it got to 20 it would give him brain damage. He didn't say anything about if he had it for a longer time though. You should ask your doctor about the time length for having it.
Hope it gets better. Keep us informed!
