Doll Annabella, Teddy Klaus, and Lion Leo feel that everything is happening too fast. Overnight, everything changes: the alarm clock rings, Lena jumps out of bed, grabs her backpack, and runs to school. Because she is now a schoolchild! But do schoolchildren even play with dolls and stuffed animals? Does Lena still have time for that? Doesn’t she need to learn to read, write, and do math? However, in the very first week of school, the children are allowed to bring their favorite toys. And the teacher even brings her own teddy bear! This makes school fun and a real adventure - not just for schoolchildren! A beautifully illustrated picture book about growing up and true friendship.
