Even though, as far as we know, babies are generally not considered as smart as children or adults, there is one thing that they can often sense: pure evil. If a baby is in the room when something bad happens, it will almost always start crying, even though there's no way it can know what's going on. As another often-used example, when the baby is picked up by a villain, it will automatically start crying regardless of whether the villain has done something to it or even looks scary. Makes a little
more sense in cases where the villain in question is known to eat babies
, though not much, given that the baby isn't terribly likely to be aware of that.
