So while this part, where they would die if left alone, is certainly right
Where did I say that the babies would be left alone and abandoned? Apparently you are unaware that in human communities with low technology, infant mortality can be pretty high alarmingly. You're also apparently stating that parents looking after children is not a "state of nature." (Or you're ascribing that to me, which, given you're alone in this, indicates you need to work on reading comprehension.)
