After having two sons, the speaker wanted to have a daughter and researched ways to increase the odds of conceiving a girl. She found a program called "Prince or Princess" that provided an easy-to-follow plan for choosing a baby's gender through diet, fertility awareness, and conception timing. The program claimed to avoid mistakes made by 87% of parents and explain factors like a woman's cycle and diet that could sway the chances. However, the speaker notes that nature may override any plans and the baby should be loved regardless of its sex.
