Is There a Nanny Cheat in The Sims 3? No — But Here Are Workarounds

No dedicated "Nanny" service exists in The Sims 3 base game or expansions. (Added in The Sims 4: Parenthood / Base Game update).

Workarounds for Childcare

1. testingcheatsenabled true → Shift+Click Sim → "Make Happy" (fills needs, removes negative moodlets). Shift+Click Child/Toddler → "Trigger Age Transition" (skip care phase).
2. Hire Services (Base Game): Phone / Computer → Services → Maid (cleans), Repairman, Butler (Late Night EP: cooks, cleans, repairs, cares for children). Butler is the closest to a Nanny.
3. motherlode (50k) → Buy best Crib, High Chair, Toys, TV. Hire Babysitter via Phone → Services → Babysitter (Base Game). Costs ~$75/hr. Stays until parents return or shift ends.
4. Family Dynamics: Move in Grandparent / Teen Sibling → Set "Friendly" interactions → They autonomously care for toddlers/children.
5. Mods (PC Only): NRaas MasterController + NRaas StoryProgression allow configuring autonomous care. SimLogical "Nanny" mod (older, may need update).
