@Lauren This! Although its flushed out through their poo, so babies poo may look a bit different than the average breastfed poo until the jaundice clears.
Yes definitely pump after every feed and give bottle, it will help with your supply also. My first had jaundice and helped x
My LO had jaundice and the way to get rid of it is to flush it out through their pee! So by giving her more milk, we were able to get rid of it! Hope it helps :)
