How does Moore hint at Tutu's deep-rooted fear of losing her mother early on in the book? How do those fears play out when Tutu grows up?

Moore includes several passages where Tutu's fears of losing her mother become evident even when not explicitly stated. For example, when her cousin from Lai comes to live with the family at Caldwell, Tutu begins to cry and begs her father not to replace her mother. Tutu interpreted the arrival of her older cousin, who acted as nanny for the girls, as the arrival of a maternal figure who had the power to exclude Mam from their family dynamic. Her reaction shows how deeply she feared losing her mother and is echoed later on when every time her father leaves the family unit to go look for food, speak to someone, or otherwise do what he can to protect them...
