Everyone knows babies can't talk, but if they could, they'd have a lot to thank their older siblings for -- whether it's giving them extra licks of an ice cream cone, teaching them songs to sing, or not letting them put sand in their mouths. This big thank-you of a book is sure to add an extra layer of appreciation to any sibling relationship. Julie Markes's sweet text and Laura Rader's humorous illustrations will delight the entire family.
