Yeah, alot of people are against circumsision themselves (me included, but I try not to judge other peoples decisions ) but after your son is born your midwives, paed & baby health nurse should be able to point you in th right direction.
There is alot of controversy surrounding the topic, just be careful of backlash some people in the medical industry (not all, but some) may have an oppinion. Don't take it to heart.
It may be hard finding a doctor who will do it. Not as many do without medical or religious reasons these days.
I've heard costs are around the $500 mark, but can widely vary depending on age & what procedure is done.
