Dear Doctor, I  have a 3 week old son -born pre-term by 4 weeks ( expected 29th Feb, born on 27th Jan). His birth weight was 2.85kg which went down to 2.4kg by 7th day. He developed hyperbilirubinemia on the 3rd day and required 48 hours of phototherapy ( TC bilirubin was 15.4 on 3rd day and came down to 12.8 on 4th day evening) and then we came home.  However he turned yellow again on 8th day and bilirubin count went up to 19.4, So our peadiatrician asked us to admit him for additional phototherapy session . At the end of 2nd day of therapy, TC bilirubin came down to  9.8 and we can back home again (on 10th day).Since then:- He is feeding well and passing urne 6/8 times a day and passing yellow stools on alternate days- He has gained some weight and now weighs about 2.9 Kgs- His palm and soles are pinkish, but face, white of the eye and gums still have some yellow tinge Questions: Is this a cause of concern? Do we need to repeat the bilirubin test? Is his weight gain fair enough? Any other suggestions? Thanks for you advice
