Make an "Emotion Book," which is targeted toward toddlers and preschoolers. It should have at least ten pages, each featuring either a drawing of a person experiencing an emotion (for example, happy, sad, worried, scared, confused, bored, excited, angry, tired, calm/content)
or a photo from a magazine or the internet depicting such an emotion.
Then write text for each page that would be easy for young children to understand and that is geared toward helping them talk about
emotions.
The important things are that it is attractive and engaging for this age group and that it effectively teaches the child about emotions.
