Not off topic. I wrote my Answer hoping someone would ask.
It's a form of genital mutilation invented in the Bronze Age to set a certain group of men apart from those who didn't belong to their society. We are aghast at female genital mutilation yet look askance when it happens to baby boys. Note too, that it was forced upon the male slaves of the Patriarchs who, like infants, had no say in the matter.
While this happened to my oldest in my first marriage, my second wife and I prevented it happening to our two sons. With vigilent hygiene which we taught them, they had a total of maybe 3 yeast infections (smegma) in childhood. The worst case was in Benny, (of “earbuds in nostrils" fame) and that was very short-lived.
The other scare tactic was telling us that there is an increased risk of penile cancer in uncut men. More recent long-term studies have debunked this.
I believe that if you belong to a religion that still mandates circumcision, that it can certainly wait until the day of reckoning, which is 13-years old in the Jewish tradition. It also seems more in line with how it was done in ancient Canaan. After all, both Abraham and Ishmael were at least that old!
After delivery and while she was still sedated (it was a C-section), and while I was in the nursery with my new pride and joy, a nurse or other staff person convinced my wife to sign the consent forms. And they KNEW of our stance beforehand! They mutilated our baby against our wishes. And the insurance company paid them for it!
