We brought this book to try and explain to our 2yr old that we were moving house soon. As yet we have not used any of the stickers because we are now using the book as a 'read-along' story. There are small illustrations to show where the stickers should go, and when reading the story we get our son to tell us what those illustrations are (therefore learning). Most of these illustrations are the key words heard when moving i.e. van, boxes, carpets, plants, matress etc etc. He still has no idea there are stickers as yet, but its been a great way to try and get him to understand and also 'read' the pictures. So in that respect it has been really useful.
All in all I think he is still a little young to understand the concept of moving house, but still a great Usbourne book. We also brought the normal book too, but since we have started 'reading' this book, we havent picked up the normal book, so would recommend this one rather than the normal book.
