Why do you assume there was no bas kol for a child that died r’l??
I’m not referring to a case where someone took his own life (which is a shaila in hashkafa altogether if he ca? reduce his allotted time that way; IIRC the Chovos Halvavos says not), but a case where someone was allotted only a few years. It makes no sense that he would have a shidduch set aside if he was not destined to grow old enough to marry.

I believe that the ribbono she’ll olam created a shidduch for everyone.
I have full faith in the words of Chaza”l, even when I don’t understand them. I just don’t think Chaza”l ever said such a thing.
