Iv'e just been researching , as I wasnt' sure about circumcision at all as far as if it's routine. I have a great book on parenting I stumbled across (Heart to heart parenting, from ABC shop) and it talked about it a bit. It cemented my decision not to.
Basically it said that nowadays it is done only for religious reasons. There is no hospital in NSW that does it routinely. There are percentages in the book but basically it's a very low percent who get it done. It says that as far as cleanliness goes, it is not proven to be any cleaner, and infact infection can be prevented by leaving the skin on. It also says you don't need to clean it when they're young (it says you shouldn't infact) and also it reduces sexual pleasure in the future.
Just some info for you. I would suggest that book, and also any other info you can get. The books great, I sat down with DH and we read it together, he's perfectly happy to leave as is if we have a boy.
Hope that has helped. xo
