Draw a variety of faces on paper plates. Each face should express a different feeling, such as glad, sad, mad, happy, sleepy, scared, and so on.
Hold your toddler in your lap and read him a story that expresses some emotions.
When an emotion arises in the book, pull out the appropriate paper plate face and hold it up to your face.
Explain to your toddler what vocabulary words go with the emotion and let your toddler make a similar face.
