My boys are not circumcised and my only daughter doesn't have her ears pierced.
My son will be having it done. Definitely!!!!
I feel that decision is no more different than waiting until a little girl is old enough to decide on ear piercings since that is cosmetic. It does vary depending on your geographical location. I had my four year old circumcised as an infant because his father was military and informed me of the fact that older uncircumcised men are more susceptible to catching stds. But again it up to the individual parent. I just don't understand the bias against it when people are so quick to make decisions regarding pain and beauty for a little girl. I'm preggo now with one and she will gets hers done when she is old enough to ask.
Also you should not push the skin back until it retracts on its own. My son is 2 and it hasn't retracted, our pediatrician (who is against circumcision) said it usually retracts on its own around 5 yrs old. Then you have to teach them to push it back and clean.
I didn't do it because I did the research and couldn't put my little boy through that. People say it's harder when they are adults but I don't agree. None of my brothers were circumsized and then one of them at 18 decided to have it done. It was a simple in office procedure and he healed up quick. My other two brothers are in their 20s and 30 and never have wanted it. I think it's good to leave it up to the boy to decide later.
