It's less that hospitals are pushing circumcision and more that there's a discharge checklist everyone is working from and the circumcision question is on it. The repetition is some combination of verifying your answer and/or people not reading the notes other people have written when they document your answer. If your answer were "yes, we want a circumcision," they'd be asking you repeatedly just the same until they actually did it.
It shouldn't even be legal, much less on a checklist. Doctors will swear up and down on their oaths or whatever other high horse when it comes to euthanasia, but mutilating children without their consent is all good!
