Each day older the baby, the high threshold they have for bili, so the number may seem high but it isn't for the age. My first son had severe jaundice, had to be hospitalized, IV, blue lights... and still after he was a yellow baby for a while. I kept asking about it and was told by multiple doctors the same thing - it takes a while for the bili to flush out, and there is higher tolerance day by day. I had to supplement with him; my milk supply was never good enough, even pumping like crazy. Used the hospital pump, manual pump (avent I think), then medela pump-in-style. Also, to echo what Patty said - wake him up to feed. My first son would gladly sleep through the night at 3 days old - I had to set my alarm to wake up every two hours to feed him for weeks. I was told later that babies that are born on the edge of full term aren't the best eaters. Now I have too much milk for #2. Now with my newborn son, my milk gushes out too fast and he chokes. Go figure, if its not one thing its another.
