I'm training as a BFC with the NCT and today at a drop-in, came across a mother who had a baby who'd had what sounded like mild jaundice. (I wasn't seeing the mother in any official capacity, but sat in.) The MWs at the unit she gave birth in reacted rather extremely - they said there were new NICE guidelines in treating jaundice in newborns, and after a bilirubin test they gave a day-old baby formula because obviously, the mother was still producing colostrum and they said the baby needed 'food' to clear the jaundice.
She, meanwhile, was told to express, and ended up developing mastitis. She was confused and upset about this advice, but felt she had to follow what they were suggesting because she had a day-old baby and no experience of breastfeeding.
I've tried to track down these new NICE guidelines - I www.nice.org.uk/nicemedia/live/12986/48578/48578.pdf think these are they - and I can't see anything that says that a baby with mild to moderate jaundice should be given formula rather than allowed to breastfeed normally and wait for the colostrum to change to mature milk. This MW unit has UNICEF accreditation, by way way, and I don't understand why they were intervening in a case like this, that the mother said wasn't serious. (The baby wasn't hospitalised, so I presume it can't have been severe jaundice.) She feels that it got in the way of establishing breastfeeding, and is sure that the expressing she was told to do caused her mastitis. 
Any thoughts on this? I was rather alarmed to see mild jaundice treated like this - DS had mild jaundice, as many babies do, and I was just told to breastfeed regularly and frequently, and to keep him close to the window!
