ELI5 Why do babies cry? Wouldn't this be an adaptive nightmare for early humans who had to deal with predators?

Explained! Thanks for the insight!

Babies are cared for in the group. A group of humans is going to be loud anyway, so having a baby cry doesn't particularly add to that loudness. And very few predators would attack a group of armed humans. The crying is a good signal however that this baby needs to be attended to (and is in fact ridiculously annoying to people so we can't ignore it) and it is also a good way to help find a child should they ever get lost. Might it draw predators near in that situation? Yes, definitely. But a child without a group is pretty much dead for anyway. Better to run the small risk of being caught be a predator with the chance that someone might find you VS staying quiet, lowering the risk of predators catching you, and then starving to death.
