My babies naval was normal after birth, but from past 2 to 3 weeks I notice the naval is buldged n it's popping up. is it something serious to be looked into or how to treat the same.

A. the child is having umbilical hernia which is very common in children and goes away by maximum 2 years of age. with growing age it regressesz and goes inside it does not require any intervention or treatment before 2 yearsz if it is non complicated. meet your doctor once who will tell you whether any intervention or wait and watch policy is required.
