I have to grab Colby from Ian here, so I will just make this quick.
Jenni, you don't have to justify the circumcision. Its a decision you made as parents. Its perfectly fine to have done it. Its like formula feeding, or using a soother, or co-sleeping.... Every parent makes the decision that is right for their family, and no one has any right to tell you whether its wrong or not.
I wanted Greg circumcised when he was a baby, but because he was a micro prem weighing just 1 pound 9 ounces, they said they couldn't do it as the pain and trauma could have killed him. Obviously I wasn't going to advocate for it then. By the time they felt it was safe for him to do it, he was around 36 weeks gestational and I didn't feel it would be a good thing to put him through. Although he was still prem at that point, he had been around for a while and seemed to be more aware of things, and I can't imagine how that would have affected him.
So he is not circumcised, and in order to keep some continuity between brothers, Colby wasn't circumcised either.
