"Children are interested in their names because they represent who they are. they're are important part of their identity and children are proud of them. Think of how often they're asked, "What is your name?" and "How old are you?"
Children's names are the first words they understand and can identify with - so they connect print with something very meaningful. This leads to an interest in trying to "copy" it by scribbling at first, and the by writing in an more conventional way."
