My Sibling succeeds by turning abstract emotions like jealousy and anger into physical objects that children can manipulate through interactive flaps. It validates complicated feelings while providing concrete games for self regulation during conflict. Books in this family share a focus on emotional literacy, using tactile elements and honest storytelling to help children manage social friction.

Reach for this book when your home feels less like a sanctuary and more like a battleground due to sibling bickering, perceived unfairness, or the arrival of a new family member. Rather than a simple story, this is a therapeutic tool designed to help children process the complex soup of emotions that come with having brothers or sisters. It provides a structured way to talk about the physical and emotional space siblings share. Isabelle Filliozat, a renowned psychotherapist, uses interactive elements like flaps and activities to move beyond 'be nice' and into 'how do I handle this feeling?' The book addresses jealousy, the quest for justice, and the deep love that often gets buried under daily frustrations. It is perfectly suited for children ages 4 to 8 who are learning that two things can be true at once: they can be angry with their sibling and still love them dearly.
