I just want to jump in and say that explaining you don't see religion as a valid argument is a pretty bold statement. If you're not religious then sure, it may not be valid for you but for those who are I think that's pretty rude to say. You can just leave it at you don't agree with it, no need to pull in others beliefs. I would never turn around and say you must circumcise because I believe that's the only right thing to do. Because thats also wrong and offensive.
Foreskin Retraction: As noted, the foreskin and glans develop as one tissue. Separation will evolve over time. It should not be forced. When will separation occur? Each child is different. Separation may occur before birth; this is rare. It may take a few days, weeks, months, or even years. This is normal. Although many foreskins will retract by age 5, there is no need for concern even after a longer period. [1984 version only: No harm will come in leaving the foreskin alone.] Some boys do not attain full retractability of the foreskin until adolescence.
Hygiene of the Fully Retracted Foreskin: For the first few years, an occasional retraction with cleansing beneath is sufficient.
Penile hygiene will later become a part of a child's total body hygiene, including hair shampooing, cleansing the folds of the ear, and brushing teeth. At puberty, the male should be taught the importance of retracting the foreskin and cleaning beneath during his daily bath.
My DS is circumcised and we would have done it again if this one had been a boy. DH is as well. I don't know if it's a regional thing, but most people around here do circumcise. I think it's a family's personal desicion and there is no right or wrong. I certainly did not mutilate my son and find any reference to that offensive. I will say that if you plan to circumcise and your son ends up in the NICU, they will not do it in the hospital. We had to have it done as an out patient procedure a few weeks later.
DS1 is 7. DD is 1. DS2 is coming in late April.
