That's Not My... (book series)
That's Not My... is a series of baby and toddler children's books written by Fiona Watt, illustrated by Rachel Wells and published by Usborne Publishing. Every book focuses on a different subject, which have included animals, vehicles and people. The first book in the series was That's Not My Puppy... which was published in 1999. Each two-page spread of the books contains a different brightly coloured picture of the subject with different attributes represented by a material. The reader is introduced to the different versions of the subject of the book with the phrase "That's not my". The inclusion of materials creates a sensory experience for the reader as they are invited to feel the material and identify why the subject on the page is or is not the correct version. By 2019, the That's Not My... series had sold 6.4 million copies of over 50 books and made over £30.6 million. As of July 2022, there are 72 books in the series. Format 
The books in the That's Not My... series are picture board books targeted towards babies and toddlers. They are part of the Usborne "touchy-feely" collection of books; the collection consists of books which contain patches of material on brightly coloured pictures which the reader is invited to feel. The Oxford Companion to Children's Literature (2015) describes the That's Not My... series as "novelty books", which are books which contain "an element other than paper or card". Each book is square and made out of cardboard. Every two-page spread contains a different picture of the subject of the book. The subject of the books include animals, vehicles, people (such as pirates and Santa), and fantasy creatures. In each book, different attributes of the subject are represented by contrasting materials. The material is incorporated into the picture itself—including on the front page—rather than being placed at the side of the page. For example, in That's Not My Elephant... (2011), the material patches cover the elephant's ears, trunk, tusks, tail, tummy and feet. Watt has stated that it is important for the materials to vary in tactile nature throughout the book, and she gets inspiration for materials from her daily life. According to the Oxford Companion to Children's Literature, the use of different textures encourages "independent exploration" of the book by the reader. Watt has said that the formula of the books is "deceptively simple". She says that the success of the books is likely due to the combination of the "tactile and sensory experience" along with a comforting repetition in the text. The pictures in the books are simple and brightly coloured. Watt said that the bold colour choice was intentional and she did not want to use "soft baby pinks and blues". The reader is invited to feel the texture and identify why the picture isn't the subject of the book, prompted by the text "That's not my". For example, in That's Not My Meerkat (2013)..., one two-page spread reads "That's not my meerkat. Its cheeks are too squashy." The final two-page spread reveals the correct subject; in That's Not My Meerkat..., the correct meerkat is revealed by the text: "That's my meerkat! Its tummy is so soft." With this setup, the reader is encouraged to work through the book until they find the right creature, person, or object. In the book Precursor Math Concepts: The Wonder of Mathematical Worlds with Infants and Toddlers (2021), the authors identify That's Not My Puppy... as an example of a book which encourages interaction between the child and adult and facilitates an understanding of "attributes". They write that the discovery of the correct subject at the end of each book amounts to a "happy ending". Each two-page spread of every That's Not My... book also includes a picture of a mouse. The mouse is sometimes accessorised to match the environment of the subject; in books with underwater subjects, for example, it wears swimming gear including goggles. Watt does not name or gender the mouse, although she had said that many readers believe that the mouse is the one collecting the subjects of the book. Watt also does not imply the gender of any of the subjects of the book where the gender would otherwise be ambiguous. The one exception is That's Not My Bunny... (2005), in which the bunny is identified as male. Background and publication history 
The That's Not My... series is written by Fiona Watt—who is also the editorial director of Usborne Publishing—and illustrated by Rachel Wells. They have collaborated with designer Non Taylor since the inception of the series. Watt's name appears on only some of the That's Not My... books, which Watt says sometimes leads to a misconception that "Fiona Watt" is a pseudonym. Every idea for a That's Not My... book begins in a meeting with Usborne executives, where they decide upon a subject for the book. Watt then comes up with a list of attributes for the subject. Peter Usborne, the founder of Usborne Publishing, was not initially interested in the idea of the That's Not My... series because he did not like its negative title. He later changed his mind, and the first book in the That's Not My... series—That's Not My Puppy...—was published in 1999. Within the first eleven years of its publication, the book had sold 900,000 copies. In 2019, Usborne held celebration events for the 20th anniversary of That's Not My Puppy... in collaboration with the National Literacy Trust's Read On Nottingham campaign. As of July 2022, the That's Not My... series has 72 books. Reception
