Let kiddos create their own story on and off the pages! Friendship Books ($18) prompt tots to record thoughts and memories in a diary-like book, which is then shared and built upon by friends. Based on traditional German memory books, these tomes encourage kids to fill in personal information about themselves (favorite music, athletes, etc.) and then have their friends do the same — adding stickers, drawings, and their perspective. The book's owner can share the text with up to 30 friends. Available in school, pet, and animal themes, the books encourage social skills.
