Now I'm 5, I can: Zoom around on my bike! Read my first book! Start school! Birthday in a Box is exactly that—a whole lot of birthday fun packaged up in a keepsake box. It has everything a child needs to help them celebrate their birthday in style, including a hardback picture book about the joys of turning five, a fun puzzle, a birthday badge letting everyone know their age, and a roll of 50 birthday-inspired stickers.
