What is the maximum depth of a woman's or a girl's deep innie navel?
My daughter and I were perplexed as to why her belly button seems to be
congruent to mine in depth and in width even though she is a teenager and
I am in my late thirties. Are umbilical cords always the same size and
does that determine the size re: depth and cirumference of the female
navel? Because this has baffeled us so, I am writing to you to put our
curiosity to rest. It is driving us crazy? Thank you in advance. (This question is raised by one of my female friends who is in her late thirties and has a teenage daughter whose navel in depth and circumference is totally similar to her mother's deep navel.)
