May the father perform the bris?
According to Halakha, every Jewish father is supposed to circumcise his own son. Nowadays, the father usually wants a proxy to perform the circumcision as for him, so he appoints a mohel. Therefore, whenever the father requests to do the bris himself, I act not as a religious proxy, but as a circumcision helper. I perform all the preparations and set up everything so that the father simply has to do the one crucial act. Afterwards, I put the bandage on myself.
