The Emotion Book Set is best for ages 2–5. At ages 2 and 3, children begin naming basic emotions like “happy” and “mad” and show early signs of empathy—for example, looking upset when someone else cries. Between ages 3 and 5, they learn words for more complex feelings like “proud” and “lonely,” begin connecting emotions with body cues, and build early perspective-taking skills which is a foundation for empathy. As their emotional awareness grows, children start trying out strategies to manage their feelings but still need guidance from a caring adult. These books give caregivers the tools to model, discuss, and practice healthy ways to navigate big emotions together.
