This set of books contains six books: hide-and-seek for animals, hide-and-seek for animal coats, hide-and-seek for toys, hide-and-seek for fruits and fruits, hide-and-seek for vehicles and hide-and-seek for clothes. This set of books conforms to all the principles mentioned above, such as thick paper blackboard writing, simple graphics, simple and bright colors, and clever digging structure, which has a strong appeal to babies. My snowball started reading picture books when she was seven months old. At that time, I bought picture books for the first time, and I bought dozens of them at once. It turns out that only six of these books can be read by her, and the others are not suitable for her age or she doesn't like reading them. Among the six books, Snowball likes watching clothes and playing hide-and-seek best, because this book is the closest to her daily life and the easiest for her to understand. For example, if I turn to the page of pants, I will tell her that this little brother is wearing pants and then point to her pants, and she will understand. Every time I see this page, she will point to her pants and then point to mine. [America] Nina Langdon This is a set of hide-and-seek picture books that attract babies to read through the holes of hide-and-seek and look forward to the lovely images hidden on the next page. The colors of this set of books are very bright. Every page has a hole, and there are pictures behind the hole, such as cows, owls, zebras, etc. , especially on the last page of every book, there are surprises (I won't delve into them here). I bought this set of books when Snowball was ten months old. When I first got this set of books, I thought the painting style was very strange, but Snowball liked it very much, especially when I saw the last page, I would giggle every time. A few days ago, I saw such a sentence on the wall of the early education center. "Babies under one year old mainly cultivate interest in picture books." Snowball mainly read the above two sets of books (10) within one year, and read each book many times. Even though she is almost two years old now, these books are still a little simple for her, and she will still be interested occasionally. Although the number of books is small, it is this 10 book that opened the door to her curiosity about picture books and made her like picture books.
