eli5 How did people survive if babies cried how they do?

Question

Im not sure if the title made sense but how babies cry to communicate, did they do that in the like prehistoricy times. Cause I refuse to believe that people who were surrounded by bears, moose, just aggressive/kill you quick wild life, lived with screaming babies around.
