If your newborn’s belly button crusts and bleeds, it is mainly considered to be due to two conditions. First, it is caused by neonatal umbilicitis. If the child’s navel is not disinfected in time after birth, the child’s navel will show symptoms of umbiliculitis, which can manifest as redness, pus, and crusting and bleeding of the skin around the navel. The parents should disinfect the child with iodophor and apply topical antibiotic ointment such as Bactrim and Lincomycin lidocaine gel. Most of the symptoms of umbilical infection in children will get significantly better, and the symptoms of pus and bleeding in the child’s navel will slowly disappear. Secondly, it is caused by neonatal bleeding disorder. If the child has a vitamin K deficiency, it can lead to bleeding throughout the body, and the child will also have bleeding around the navel, this time to give the child timely vitamin K supplementation treatment.
