About the author
Mummo (Finnish for grandma) is a psychologist, cognitive psychotherapist and mindfulness teacher from Finland, about to retire. For years she dreamed of children’s books that would teach feelings to children and adults alike.
The stories grew out of real moments with her daughter Jasmin’s dog Jörö, and every one of Mummo’s tips came from real life – made with a full heart and South Karelian warmth. Her son helped bring the stories to life.
The real ones



Jörö, Ledi, Nalle, Valo and Karhu
Real dogs whose everyday life the stories are about.
