Sabar ya, umbilical granuloma memang common dan boleh hilang sendiri dalam beberapa bulan, tapi bagus la dah jumpa doctor sebab mereka boleh assess kalau kena treatment atau just monitor ja. A few of my mum friends' babies had the same thing, and mostly the clinic just told them to keep it clean and dry, sometimes kena cream or mild cauterization if it tak resolve, depending on how bad lah. Follow up je dengan doctor's advice since they'll monitor progress your baby's navel, okay?
