There are actually cultures in some places, particularly in less developed countries with high infant mortality rates, that it's basically expected that most babies won't make it, and they don't even name their children until they've attained a certain age milestone. If the kid reaches that point (in some cultures as old as 3) then they figure, well, this one will probably make it, and then they have a big party and give the kid a proper name and accept it into their community. Conversely, if the child dies before the age of "legitimacy," it is of course mourned but it's considered as basically a late miscarriage - it never really "lived" and wasn't a person yet.

We as a species have had to develop some tragic ways of dealing with the realities of life under harsh conditions.
