I like the illustrations in this board book, made in colored crayons. What is more important, my son likes them and we often choose this book as a bedtime story (he is 17 month old). The colors are vibrant, the animals nice, and the boy in red pajamas easy to find as a center of each illustration. Hopefully he will remember the numbers, it is a good way to introduce them. The book is sturdy and he can turn the pages himself. A good book for the youngest ones!
