XP: breastmilk jaundice/ pumping question

uscalma34

DS is 1mo old today. I noticed over the past 2 days his jaundice returned. I called the pedi and they checked his bili. It was elevated. The Dr. said it was probably due to my breastmilk. It's not quite the same as the jaundice he had right after birth. I have to stop breastfeeding for 48 hrs and then we will re-check his bili levels in 5 days. Has anyone had experience with this? Also, should I be pumping only during the times he should be feeding? How long do you suggest I pump?
