Are you referring to the infant death rate? According to Google it's only 5.4/1000, so it would only be 43.2/8000, not 57. But those deaths are contingent on the births happening in the first place, so the comparison is not apt.

(That is, you as an infant being born pay the risk of infant death in order for the opportunity to be born -- the shot at existence. On the other hand, asking carseated children to stochastically pay with their lives for the opportunity of a sibling to exist is a different matter morally.)
