Joseph it’s nice that you want it to be a short time, but you can’t go off on someone who is reading the story. You don’t know what it was, you know what you would like it to be or maybe you would like to suggest a limud zchus. But to harp on him angrily because he doesn’t share your self constucted version makes no sense.
I still think it is a more respectful limud zchus to say she left the baby in the car thinking she would be right out, then to say she just lost reality for a moment. But since I don’t know, I’m not going to insist you buy my version.
