My 19-month old son loves this sticker book probably more than any of his other toys. He is a runner, jumper, climber and typically won't sit still for more than 5 seconds, but he will sit for 45 minutes playing with the stickers in this book! We don't use the pages in the book, but he uses the stickers on regular paper. He'll put them on, then take them off, then put them on again. He is obsessed with vehicles, and will stare at each sticker trying to "take it all in." It is very difficult to find vehicle stickers, especially ones that are pictures of vehicles instead of drawings of them. This is the best bargain I've found for stickers. He's just finished all the stickers, so I'm buying another one (or two or three)!
