circumcision

Please no judgement my husband is adamant that our son gets circumcised and I'm not looking for pros vs cons. We had our boy at home and he's now almost 4 weeks old. He is scheduled for a circumcision on nov 3rd. I'm freaking out about it. If it wasn't for my husband I wouldn't circumcise him at all mainly because I don't want him to go through that pain especially being that it's not necessary. I'm looking for encouragement that it's not as terrible as I think it's going to be. I can't stop crying thinking of him going through that.
