Lots of twists and turns, but right from the start there was a glaring sleight of hand that would never have happened in real life which set the stage for al the ensuing events. And that is that there is no day care, preschool, etc. that would ever allow a child to be picked up by someone who was not on a designated list to do so. Without that being glossed over, the entire plot can never happen. Since the series was about parental responsibility, it rang hollow that the schoolโs negligence was never even discussed as an issue.
