Edgy! No one has ever considered the mortality of their children ever, or contemplated the difference between death before and after the realization of potential. Wow!

It’s not exactly a rational feeling; it’s not like this baby was going to die through lack of parental effort or care or anything else that the parents have any real control over, so it’s not like they could have done anything differently.
Nonetheless, it can make you feel like an utter failure of a parent. To some people (I admit, not everybody), that is absolutely crushing.
It only looks irrational if you don't understand what people and feelings are.
