Feed lots and lots and lots. It will raise the blood sugar and flush out the bilirubin. Jaundice, when it's true physiologic jaundice, which is what most new babies have isn't really dangerous. It's only truly dangerous when it's the result of liver problems (which is likely isn't, though the treat them both the same just in case). The more baby eats, the quicker it will start to flush out. So feed lots and often, we were told every 3 hours at the absolute longest, but more often if she would take it. My daughter was also born on the earlier side, just 37 weeks, but I don't think that had much to do with it. It was really because she struggled to eat to start and she just couldn't get enough milk, in part because she couldn't latch, so I was trying to BF her, plus topping her up with cups of expressed milk and formula for the first 5 days. Also, lots of skin to skin whenever your LO doesn't need to be under the lights will help too. Hang in there. It's really hard. That whole first week is one long stressful blur of a day with no sleep and lots of doctors and midwives stressing us out, but persisting and feeding lots really paid off.
