This is a cute teacher-appreciation story where a classroom of miscreants is used to taking advantage of their too-nice teacher Miss Nelson. They ignore her instructions, they make paper airplanes, don’t focus during story time, and so on. They’re finally forced to behave when Miss Nelson goes missing and is replaced by a horrible, mean, dictatorial substitute teacher. They’re thrilled when she comes back… and it’s cute. The art is the kind of ugly-on-purpose drawings that are actually quite well done, and it’ll keep your toddler’s attention, even if it will get old for you upon repetition.
