favourite books and songs for children

Dear parents, we are designers of a brand new educational website for children. Originally we began this website in our own country but have recently grown to incorporate other countries and languages. Our goal is to create the best online activities for children and we were fortunate to do just that in our homeland. To make this experience unique for your country, we would love to hear more about the fairy tales, songs, and books your children love! What are some stories that all children know? For example, in France, they all read Charles Perrault, in England - Edvadr Lear, and in Russia - Aleksandr Pushkin. What is popular in your country? What fairy tales, songs, nursery rhymes, and verses for small children would it be considered a shame not to know?
