Writing gives children a way to share their voices and ideas with the world. Even in early childhood, the purpose of writing is to communicate. All young children have messages to share, and writing is one tool they can use to communicate those messages. For young children, it is quite challenging to form and remember messages while also figuring out how to put them on paper. Studies demonstrate that executive function skills, including self-regulation, are needed so that children attend to and persist in this complex task. Writing engages young children across developmental domains and activates motor, cognitive, and socioemotional learning. This article presents why early writing is so important and intentional supports for early writing.
