Generally speaking it can be a sign there's something wrong about the baby if it doesn't cry right after coming out. It could indicate a weakness of some sort. Of course it's not 100% certain, but it's quite a universally observed indicator. It also expels liquid out of the baby's lungs, mouth, and nose. In the end the ways a newborn can communicate are few, and crying is one of them.

It was a self-sacrificing technique. They tend to be strong in most fiction. Well, not only in fiction.
