Hello, Increased bilirubin is a common problem in newborns. And, if it happens in the first week, it is more likely to be physiologic in nature. Continue with phototherapy if advised. If 48 hours of phototherapy have been completed, continue with keeping the baby warm and exclusive breastfeeding. Exclusive breastfeeding means you only breastfeed the baby. No water, no pacifiers, no sippers. An ideal interval between breastfeedings is 2 hours, but it can be more or less based on when the baby cries. That is known as on-demand breastfeeding. Additionally, do not bathe the baby till the umbilical stump falls off. Till then, sponging is advisable. Kangaroo care is another aspect that is important, not only for exclusive breastfeeding but also for improved bonding between you and the baby. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Pranav Balakrishnan
