It shouldn't matter, as you shouldn't circumcise the child in the first place. Do you realize what it entails? An infant, with no power to defend himself, is attacked with a knife and has the most sensitive part of his body hacked away? The child often goes into shock from the pain. The mutilation has long-lasting consequences, as it stops part of the brain from developing and doubtlessly leaves an awful trauma in the boy's memory. Circumcision is a horrible, barbaric rite that has no place in civilized society, no matter the culture.
DON'T DO IT.
