In The Life Changer, Ummi (the main character) also has four children namely: Omar, Teemah, Jamilah and Bint. Personalities of every child differ and are an expression of his/her age and status in the family.

The eldest is a teenage boy Omar just admitted to the university and thus the center of pride and enthusiasm of the whole family at the beginning of the novel. Teemah is snarky and inquisitive, whereas, Jamilah is more introverted. Bint is the youngest and she is bright and her teacher regards her intellect also admires her swiftness of thinking and confidence in the scene where they open up the seven-day novel.

The relationships of the kids of Ummi indicate a very close interconnected family that has mutual respect and a sense of humor. The brother and sister are always full of joy, teasing one another and arguing, sharing stories, which once again outlines a healthy and communicative family.

They are different in age and personality, but they can listen to each other as well as to the mother, demonstrating the balance in love, respect, and curiosity. This gives life to life lessons that Ummi gives them through her storytelling, not only to entertain them, but to educate them about the world and prepare them to face life, especially when Omar moves to the university stage.
