Philip and his twin sister Elsa visit the pediatrician for an examination and to receive a health certificate so they can start exercising. Philip is very eager to learn polo, but at the same time, he feels an indefinable emotion, as if something is bothering him. But why does he feel this way? The pediatrician reassures him by saying that what he is experiencing is stress, something normal, like a magical potion that makes us stronger. As long as the stress does not last too long.

Through the pages of this book, we embark on a journey of understanding, supportively approaching the worries and restless thoughts that often overwhelm children in the challenges of their developmental journey. With scientific knowledge in simple terms, this story explains the difference between good and bad stress, discusses the effects of harmful stress, and offers guidance for more effective management of it.
