No Nintendo DS Sims game allows marriage, pregnancy, and household management like the PC/Console versions.
| Game | Family Mechanics | Verdict |
|---|---|---|
| The Sims 2 (DS) | Single Sim. No marriage, no babies. Roommates only. Story missions | ❌ |
| The Sims 2: Pets (DS) | Pet care focus. Human Sim cannot marry/have kids | ❌ |
| The Sims 3 (DS) | Single Sim. Skills, jobs, wishes. No household, no aging, no babies | ❌ |
| MySims / MySims Kingdom / Agents | Chibi town building. No family simulation | ❌ |
Conclusion: If you want The Sims with husband/wife/baby/house on a Nintendo handheld — buy a Switch and play Tomodachi Life or get a Steam Deck for Sims 4. The DS games are spin-offs, not the life simulator.
