Been there, done thatMy first was born by cesarean. I had no fight left in me to argue the circumcision. My dh took him down (while I was still unable to get out of bed) and actually watched this procedure. He had no problem with it. He reasoned that since he was circ'd, our son should be, and he didn't want confusion/discussion about why the father was circ'd and the son was not.
Scroll ahead 7 years to our second son... I realized in that time that our 1st son had NEVER seen his father without clothing, and I'd had an incredibly empowering homebirth. Circ didn't happen, and tough luck!
Now, go ahead 2 years... The second son is running around the house, naked as always, with a clothes pin attached to his foreskin.... and the first son asked me, "Why can he do that, and if I did, it would really hurt?" I told him exactly what pdx.mothernurture said, and the discussion never came up again.
My boys are now 18 and 11, and it doesn't make any difference. They are both private, nobody sees their privates, and it just doesn't matter.
The only one who cares is me. When I see my younger child, I think how nice he looks. When I see my husband and older child, I think, "They look so naked, so exposed!" My, how the world changes!
Good luck with your decision. Each one of us is an individual, and what is right for one may not be right for the other. And, you cannot fix the past, so give yourself credit for doing the best with what information/strength/abilities you had at the time.
