A light-skinned caregiver shares with their children the wonder of their dark brown skin as the youngest grows from newborn to toddler. "When you ask me why your skin is brown, / I will tell you that you are my favorite color." The caregiver and a child welcome a new baby, and on the next page, the trio cuddle against a warm backdrop of family photos as the text continues, "I will say that your skin was decided long, / long ago. Time was just waiting for you." Spread after spread shows the new baby growing and exploring their world with the older child by their side, and all the while, the text describes brawny bears, singing cellos, reaching sequoias, and more to prime the children's understanding of their unique personal canvases. Sze's text unspools a letter of love--a caregiver's love and the self-love it inspires--as Mata's illustrations combine gentle earth tones with vibrant, playful splashes to capture all the family adventures of a little one growing up. This is a sweet, languorous celebration of brown skin in all its infinite shades and of multiracial, multifaceted families. (This book was reviewed digitally.) Lovely.
