""When my four-year-old daughter needed a 'big-kid' backpack for the new school year, I was overwhelmed. But once I saw all the preschooler-approved features of the Wanderwild Wild Flower Explorer Backpack ($48), I was sold. This playful design was perfect for her, and all the padding and ergonomic-minded straps made me confident she'd wear it without a fuss." — KS
