Once a child starts writing there is no stopping them! They absolutely love inventive spelling. In fact I wholeheartedly agree to have the child read their own writing before formally introducing reading to them. It seems that all(4 yr olds) of the children here are entering their sensitive period for language.
Our easel has proven to be an invaluable tool in allowing the children to follow their interest at a whim.
The children also enjoy using the easel for drawing pictures to tell a story.
