my baby Belly button has been wet for 3 months and it's discharging what should we do to cure it soon

A. Hello my dear parent! This can indicate Ambalal hernia or some kind of infection. This condition definitely needs a personal medical evaluation to understand what is triggering the problem. So get in touch with your consulting paediatrician to clarify. Maintain a good personal hygiene routine for the baby and keep the area dry as advised.
