When Yumo started educating her children, her method was almost laissez-faire.
However,
The outcome of this free-range parenting method didn't appear to be positive.
Aside from her eldest daughter, who was difficult to educate from the start, her son who turned into a notorious rascal in the winter forest after experiencing laissez-faire growth, became the number one troublemaker.
He caused trouble all day long, bullied the neighboring creatures, and gave his mother constant headaches.
So,
After being nearly killed with frustration by her son Pierre, Yumo changed her educational approach.
She abandoned the laissez-faire method and chose to personally raise her children.
Then, she brought out her daughter Kalina.
