Belly button update

I called Sasha's pediatrician about my concerns about her belly button.
The pediatrician is again unconcerned and does not want to see Sasha about it. She says it does sound like an umbilical hernia, but that umbilical hernias usually go away by age 5 on their own? I questioned whether it is concerning that it seems to be growing in size. The pediatrician says no, it's not concerning. Umbilical hernias can grow and shrink in appearance at times and it is nothing to be worried about.
