My 2 month old Baby has umbilical hernia . Doctor told it will settle down in 2 years. Since last week , he has diarrhea also. Mild viral infection. With probiotics 0.5ml per day and z and d drops it's settling down. He is passing more gas and I'm able to hear a rumbling noise from the umbilical hernia protrusion. I have heard this sound while pressing it earlier. Now i can hear the noise even without touching it .. He doesn't cry on touching it. No discoloration. But after every feed or movement I'm hearing that noise. Is it due to the diarrhea problem or umbilical hernia.. should I visit the doctor immediately?
