With my first, I told people we didn't want it done. Still, we were asked several times, to the point of having someone come in and say "I'm here to take Nathan to be circumcised," at which point I argued and he argued back that "his name's up on the board..." and I yelled back "Take it OFF then!!"
With that experience, when #3 was born - #2 was a girl- I put this tshirt on him
and a post-card version of this
taped in his basinette right next to his "I'm a boy!" card with his "Baby Boy Gardner" and stats on it, etc. I also put a sticker in his chart: just like what's on the tshirt, over the area that said "Circ done? Yes __ No __". Nobody asked me that time, although I did hear on the video later, the labor nurse talking with the post-partum nurse right after delivery as they were dressing him about the tshirt I'd brought to put on him saying something about how we were very specific that we don't want it done.
Oh yeah- and since he had to be watched for 12 hours after birth because I was group b strep +, we roomed in together and the nurse came to take his vitals every so often. When she saw his tshirt she made a face kinda like "Like we need THAT shirt!" Like she was insulted I'd need it? Dunno.
