My daughter is quite cranky today, her umbilical cord has fallen off about 24hrs back, but there is a slight pus and blood. The pus was seen once before 18 hrs however, I still see slight blood wetness at the naval. No redness or coloration around the area. If it can heal on its own I would rather prefer it to heal natural (if no concerns), or is it must that I should be applying any medicine? Plz suggest. Attaching the current status photo of the same.
