Children experience all sorts of emotions: sometimes going through several very different ones before breakfast. Yet they can struggle to put these feelings into words. An inability to understand and communicate their moods can lead to bad behavior, deep frustration, and a whole host of difficulties further down the line. Like adults, they need help to recognize and verbalize their inner state. The greater their emotional vocabulary, the more likely they are to grow into happy, healthy, and fulfilled adults.
