Here are a couple of stories that I have run across in the past few weeks of parents who were in the room when the doctors were circumcising their babies, and stopped the procedure before the actual circumcision occured, but not before the foreskin was separated from the glans.
Both babies had anesthetic applied to the penis before the operation started,
yet they were still in extreme pain.
They are important to read if you are considering circumcision.
