I don't have kids, so this is a serious question. No sarcasm meant, truly.
Would a kid really cry that long if left alone for the length thought in all this?
I would have thought a kid would run out of tears or their nose would stop up to the point that they'd need to stop in order to breathe. That is a lot of crying to carry out in that time span.
If no one was offering up attention by way of leaving her in a room alone, I would have imagined the kid would get bored and start pouting or playing with toys, or something other than crying. But if someone was in the room terrorizing her or in there but ignoring her, I can see a kid breaking out the massive tears for either reason.
But, I don't have kids so I have no clue
Sorry if it sounds like a dumb question.
