Girls, what should I do? My son is 2 months old and jaundice isn't going away, we've been giving him Ursosan for a month, he doesn't lie under the lamp all the time, he cries constantly under it, the last time we checked his total bilirubin was 56, his eyes turned white now, I see they're turning yellow again, I removed the formula and fed him only breast milk, is it possible that this caused it?
