Motherly Love<br>Bob's mother was very nasty and never made him feel loved. In adulthood, he had a hard time trusting women. He finally married Kate but was unsure about having children. When she became pregnant, Bob worried about making a child happy. When he saw Kate hold the baby, radiating love, his fears dissolved.
Bob's mother never had any children.
It's definitely incorrect because she obviously had a child, who was Bob. It's difficult because the text mentions someone else having a child which perhaps confused the system.
