We didn't and won't for DS#2 due in Feb 2010 - mainly cause I figure like father like son/s, but also don't really see any benefit to having it done. And from what most other parents of boys that I know, they haven't either, so it seems to be the trend these days that most don't (that I know of) - wouldn't want my boys to feel different from the other boys at school/locker room etc. If they want it done when they are older, it will now be there choice.
