This morning my 4-year-old said, "Mummy, there are two languages, child's language and adult language". I asked her what she meant and she explained that when her friend was crying the teacher told her to read her the "owl" book. She then said, "The teacher reads the words but the child changes it." A young child may not be able to read, or retell the story using the actual words but often can retell it in their own words. A bit like a translation, as my daughter illustrated. The key factor is not the actual words, but the story behind the words.
