In My Heart
A lovely book that encapsulates how feelings really feel. Offering pictures and words to describe what a body might feel like when you feel happy, strong, angry, or sad. My only caveat is this book is definitely gendered toward girls, wish there had been images of both boys and girls to round it out. Having said that, it offers some excellent explanations of how moods transform, and provides tangible kid-friendly language to explain why we might feel what we feel.
