The book's content is disappointing & not appropriate for younger children: "You're not my friend if you don't come to my party!" and brief mention of spin the bottle. Not even a good story, in my opinion.The structure of the book is also disappointing. The vinyl stickers are only for use on the front and back fold out covers, which as another reviewer stated are already way too busy for adding stickers. The story is only 5 pages long, the other 12 pages are single use activity sheets that would entertain a 2nd-3rd grader for no more than a single sitting/day at most.While I was excited to find reusable stickers, this is not a good buy at all, especially for the price.I don't recommend it, especially not for preschoolers, kindergartners or even 1st graders, nor for any possible long term use.
