Freaking myself out!

Jennifer • Married❤️Mommy to Sofia👧🏼Elliana👧🏻Gisele👧

I was getting my LO ready for bed and when I was giving her a bath I noticed there was a pimple in her belly button. My first thought was hernia! But she the pics I seem online are huge bulging belly buttons. She doesn’t seem to be in any pain or acting different. Anyone have any advise or words of wisdom???
