Can You Have More Than One Child in The Sims 3: Ambitions? Yes—Up to the Household Cap

Yes, you can have multiple children in The Sims 3: Ambitions. The expansion doesn't impose a family-size limit beyond the base game's household cap of 8 Sims (including pets).

Ways to Add Children

• Natural Birth: "Try for Baby" interaction with a romantic partner. Random chance for twins/triplets (increased by Fertility Treatment lifetime reward or specific traits).
• Adoption: Phone/Computer → Services → Adopt Child. Choose age (baby, toddler, child) and gender.
• Move In: Marry/move in a Sim with existing children, or use testing cheats (testingcheatsenabled true) → Shift-click child → "Add to Active Family".

Requirements & Limits

• Household Cap: Max 8 Sims. With 2 parents, you can have up to 6 children/pets combined.
• Relationship: "Try for Baby" requires high romantic relationship; usually marriage/steady relationship (depends on mods/settings).
• Space: Ensure enough beds/cribs and floor space for routing.

Note: Ambitions adds careers and skills but doesn't change core pregnancy mechanics from the base game.
