I don’t quite understand what’s terrible about caring for others, what should make a child unhappy.

Her husband has a daughter from her first marriage, her mother recently gave birth to her sister. The daughter of her husband, who was a joyful, joyful child with five in school, turned in six months into one of the most backward in the class, a nervous, eternally insomniac hysteric, because instead of sleeping and studying at home, she is awaited by hell, a baby whirls, she is forced to nurse and do everything at home. She comes to us to sleep. She hates her sister.
