Grayson, you already have found the words of what to say to your niece one day.

Perhaps one day your niece if she does have it, will also ride with you and gain that strength from you.

Without question, just basic things that define female vs. male bodies, do form our self-image ..for the rest of our lives. It determines how people treat us, female vs. male.

The loss of a breast is probably another clear example...though I haven't experienced this yet..and hope not to. But far worse things could happen.

In my teens and another sister, we both had severe acne...enough that it warranted prescription drugs..pills, lotions and careful selection of certain soaps. This was one of the reasons why I was so glad to earn money part-time and get my long hair cut off. It was healthier for my skin. Recently I looked some old photos of self in teen years..those years of self-consciousness, were like muffled years lost under that angst over what...how I looked as a growing young woman. Thankfully my parents did emphasize that we work on ramping up our brains to make it through school instead of making us feel less on other things.

Looking back though, they did sense how important how we personally might feel about positive self-image. They never compared/commented on their children against one another in terms of physical looks. (or at least, I never heard it.) Amazingly 2 of my siblings had teeth braces..and my father's restaurant employer didn't offer any medical benefits whatsoever. So this was the sacrifice...that they made. None of these siblings went whining to my parents to ask for the orthodontic treatment.

I shake my head in amazement, looking back..
