Sam

Sam is a child in the same class as the alpha mums' kids, including Amanda's children Manus and Georgie. Sam plays football and requires pickup on Wednesdays as part of the group's choreographed childcare logistics. This scheduling detail catches Julia's ear, prompting her to volunteer help with pickups and insert herself into the alpha mums' social economy amid her own childcare crisis. Sam's routine underscores the precise coordination that binds the group and attracts outsiders seeking entry.
