<s>[INST] WHAT IS THE DIFFERENCE BETWEEN BREASTFEEDING JAUNDICE & BREASTMILK JAUNDICE? [/INST] Two different types of jaundice with similar names is a recipe for confusion! 

Breastfeeding jaundice is a stupid term for one but was named as such because it's Jaundice associated with poor, ineffective breastfeeding.

I never use this term and instead refer to it as inadequate intake jaundice because that's what it is. Jaundice caused by not enough intake.  Bottle fed babies fed breastmilk or artificial infant milk can get jaundice too due to the same reason, but its called starvation jaundice.  Leave it to whoever coined the term to create a negative association with breastfeeding once again, but that's a rant for a different day. Inadequate intake jaundice should resolve by week 1-2.

Breastmilk jaundice is just prolonged jaundice. As I mentioned above, breastfeeding seems to increase the odds that Jaundice is going to stick around longer.  Babies with breastmilk jaundice may have Jaundice that extends through week 2-3 or may even last a few months before their numbers decrease. Older babies with elevated bilirubin levels under 18-20  generally don't need treatment.  Source: Mattos Lactation.
