Parenting fatigue rarely stems solely from physical labor. Lifting toddlers and washing dishes takes energy, but cognitive management drains the nervous system. Sociologists classify this overhead as the mental load: the anticipatory, executive work required to keep a household operational.
The default parent tracks nap schedules, diaper counts, allergy restrictions, shoe sizes, and emotional thresholds. When a family leaves the house, that parent runs a perpetual background diagnostic. Are extra clothes packed? When did the youngest last drink water? Where is the nearest restroom?
Heterosexual family models still default to assigning this cognitive management to mothers, regardless of employment status. When fathers view their role as "helping out," they unintentionally reinforce this asymmetry. A partner who asks "What do you need me to do?" may believe they are being cooperative. In practice, that question positions the mother as the manager who must expend extra energy delegating tasks. Orr's playground observation bypassed the delegation cycle entirely.
