HAIR-PULLING HURTS! is well suited for children between the ages of 3 and 5 years old. Its topic of hair-pulling is very interesting and its simple, delightful illustrations are very engaging. It shows children how useful their fingers are and encourages them to think about the many ways they can use them. However, it emphasizes that using fingers for hair-pulling is unacceptable behavior. But the primary purpose of HAIR-PULLING HURTS! is to promote early literacy: the overwhelming use of word repetition throughout the book is an attempt to aid word retention.
