Description My Little Friend - Making a cute caterpillar as a friend is fun! But wait. Where did my little friend go? Growing On Me - Babies are no fun. They're stinky and they cry a lot. Will they end up growing on you? Level 0 - Lilac books support children's developing speaking and listening skills as well as the linking of sounds and letters. Children are encouraged to enjoy books from as early an age as possible. However, the focus of this phase is on listening to and repeating sounds, rather than on directly reading words. In our level 0 books, there are no words.
