I was born with hole above my ear and so was my daughter I believe it just genetics and possibly a birth mark ,I have two ,one hole on my ear and a dark patch on my back x
I think that’s an ear dimple. My daughter has one also but in a different spot

My sister (now in 30s) has kinda same on both ears. Its a birth mark and its said genetic. My great grand mother had same kind sooo.. maybe she got from her😬
These are dimples!
My baby has one too. It’s barely noticeable but I’ve also wondered what it is
