Has anyone else seen something like this on their baby??

When you feel her left side it feels normal but on her right side of her rib cage it feels like an indent.

I'm taking her into the E.R this afternoon to get checked out, I'm just curious if someone knows what this is and can maybe give me peace of mind.

First time mommy over here worrying about her baby ♡

Or just prayers for her that it's nothing to serious ♡♡

UPDATE:

This is what the dr said she may have and wants me to get a second opinion with her pediatrician....
