Now I'm 3, I can: Dress myself without help! Sing all my favorite nursery rhymes! Slide down the big slide at the playground! 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 three, a fun puzzle, a birthday badge letting everyone know their age, and a roll of 50 birthday-inspired stickers.
