LmaoSometimes a person, typically a woman, will have a child that's leaving the home and suddenly feel like they without. Empty nest syndrome. Anyway, to fill that void they typically have another child or get a pet
ChiChi chose another child
Worked out well as her friend has a son a couple years older and they eventually become besties
So a character that became irrelevant since the start of the sequel series wanted another kid who was also irrelevant
