Hello girls. Can anyone tell me who had problems with healing the navel?

Hello girls. Can anyone tell me who had problems with healing the navel? What did you do? The doctor at the hospital advised to treat it with alcohol, but it doesn't help. The navel fell on the 9th day, we also took baths. Probably didn't need to bathe until the navel heals. I'm very worried, can anyone tell me who has encountered such a thing? Tomorrow I have an appointment with the doctor.
