There is an excellent article on jaundice that needs to be in the arsenel of every LC. *Breastfeeding and Human Milk: Their Association with Jaundice in the Neonate*, Auerbach, Kathleeen and Lawrence Gartner, Clinics in Perinatology, Vol 4 No1, (1987), pp 89-107. The article is an excellent guide for nomenclature (ie types of Jaundice) and causes. It has helped me on several occasions with the physician who insists its breastmilk jaundice.
