This book is the perfect size to take with you on your trips out of the house. The bright colors will attract your baby's eye and all the vehicles will allow you to talk about the cars, trucks, bikes, and so on you see on the roads. Don't feel silly making the noises on the page. The combination of your child seeing the picture on the page, you saying the name of the vehicle and making the sound of the vehicle, and you pointing out those vehicles as you drive or walk is a powerful learning experience for your child.
