Hi, I am Dr Suresh K Yadav MD (paediatrics), I had gone through your question and understand your concerns, Your baby is 13 days old , 14.5 bilirubin level is not normal for this age . She needs investigations and examination to know cause of this increased bilirubin. If everything is normal it may be simple exaggerated physiologic jaundice or breast milk jaundice which sometimes takes time to decrease . But rising level is a reason of concern and may require interventions like phototherapy . Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions Take care.
