[The Truman Show] How did they keep the other kids around Truman from spilling the beans when he was a child?

This isn't just about child actors' acting skills being a problem; the real question is how they kept the kids from flat out *telling* Truman, or otherwise letting the truth slip.

Kids can be terrible when it comes to dealing with an outsider. If they all knew that Truman was the special kid that they were all working around, then they'd almost certainly start to ostracize him, just as surely as if he were the weird kid in class, and possibly worse, because they all basically have to work *for* him, without his knowing.

Add to this that kids are not great at keeping secrets. You'd think that one way or another, eventually one of them would tell him; either in a fit of anger ("Oh, yeah, Truman? Well you aren't even a real kid! We're all just actors! So there!") or else in a misguided movement towards friendship ("Truman, we're super good friends, so I have to tell you the biggest secret that you'll ever ever hear...")

So how did the producers prevent this from happening? How did they keep the other kids from treating Truman weird for being the only one not in on the big secret, and how did they keep any of them from just telling him the truth?

He _never_ had good, long-term friendships as a child, which is why he's fairly detached and formal with the people around him. He greets his next-door neighbors from twenty feet away, with a robotic and... frankly... _staged_ performance.

This formal, proper upbringing helped ensure that he'd be controllable and acceptable for TV, _and_ avoided getting him in situations like you mention. It was a gamble, of course; it could have turned him into a sociopath, but hey, Dexter turned out pretty popular too, and with some careful editing...
