The Sims 4 is a chaotic game by design, but nothing quite matches the self-inflicted torture of the 100 baby challenge rules. It’s a marathon. Honestly, it’s more of a test of human patience than a casual gaming session. If you’ve ever tried to manage three screaming toddlers while your Matriarch is passing out in a puddle of her own making, you know exactly what I’m talking about. People think it’s just about having kids. It’s not. It’s about resource management, timing, and exploiting every single game mechanic available to keep your sanity intact.
Most players jump in thinking they can just wing it. They can't. You’ll fail within two generations if you don't understand the restrictive, often frustrating framework that makes this challenge a community staple.
The Foundation: Who is the Matriarch?
Everything starts with one Sim. This is your Matriarch. You can make her look however you want, but her traits matter more than her hair color. Most seasoned players suggest the "Romantic" or "Alluring" traits because, frankly, you don't have time for a slow burn. You need to get these guys into bed as fast as possible.
The 100 baby challenge rules are very specific about her lifestyle. She cannot have a job. Not a traditional one, anyway. She has to stay on the home lot to care for the literal army of children you’re about to produce. This means your income has to come from things like painting, gardening, writing, or even selling collectibles you find in the backyard. It's a grind. If she dies before the 100th baby is born, the challenge doesn't necessarily end, but it gets a lot more complicated. The youngest daughter takes over as the new Matriarch, and the cycle of suffering begins anew.
You can’t just use any donor, either. Diversity is the name of the game here. A Matriarch cannot have more than one pregnancy with the same donor. Once a Sim has fathered a child for the challenge, they’re effectively dead to you. Move on. Find the next guy at the nightclub or the library.

The Rules of Engagement (and Aging)
Aging is the biggest hurdle. In a normal game, you might let a kid grow up naturally. Here? You want them out of the house the second the game allows it. But there are strict gates. You can’t just bake a cake and age up a baby whenever you feel like it.
- Babies: They stay in the bassinet until the game forces them to age up. You cannot trigger this early.
- Toddlers: This is where the real nightmare begins. You can only age them up once they reach level 3 in all skills. Or, if you’re a perfectionist, level 5. Most people stick to level 3 because five toddlers with level 1 potty skills is a recipe for a deleted save file.
- Children and Teens: They have to get an 'A' in school. Once that notification pops up saying they are an A-student, you grab that birthday cake and get them out of your hair.
It sounds simple. It isn't. When you have seven children in a tiny house and only one bathroom, getting a child to focus on their homework is like herding cats. Very loud, very angry cats.
Managing the Household Chaos
The 100 baby challenge rules state you can never hire a nanny. That’s the big one. You are the sole caregiver. No professional help. No "Services" menu to save your soul. However, you can use your older children. Teens are basically unpaid interns in this challenge. They cook, they clean, they help with homework, and they keep the toddlers from being whisked away by social services.
Speaking of social services—if a child is taken away, they don't count toward your total. They're gone. It’s a zero. A waste of nine Sim-hours of labor.

Lot traits are your best friend. If you have the "On Ley Line" trait from the City Living expansion, use it. It increases the chances of twins and triplets. While that sounds like a death sentence for your Matriarch’s energy bar, it’s the only way to hit 100 babies before you personally reach retirement age in real life.
Money, Space, and Survival
You start with the standard 20,000 Simoleons. It vanishes fast. You’ll spend most of it on beds. Bunk beds were a godsend for this challenge when they were finally added to the game.
Don't buy a big house early. You can't afford the taxes. Start small, build a "baby wing," and keep the kitchen central. You’ll be doing a lot of cooking. Fruit salad is the move—it doesn't require a stove, so there's no risk of your Matriarch burning the house down while she's sleep-deprived.
There's a common misconception that you can't use rewards. You can. The "Never Weary" or "Steel Bladder" rewards are essentially legal cheats within the 100 baby challenge rules. Save your satisfaction points. Spend them on things that keep your Matriarch awake. She doesn't have the luxury of sleep.

Moving Toward the Finish Line
The challenge ends when the 100th baby is born and reaches the "Young Adult" stage. It usually takes multiple generations. Keeping a spreadsheet is actually pretty common among the hardcore community. You need to track who the fathers were, what the kids' names are, and what number you're on.
Don't forget the "No Mods" rule that many purists follow. While some people use MC Command Center to tweak things, the official challenge (popularized by users like SnarkyWitch) forbids mods that give you an unfair advantage, like increasing household size beyond eight. Stick to the eight-Sim limit. It’s what provides the difficulty.
Your Practical Checklist for Success
If you're actually going to start this today, do these three things first:
- Pick a lot with the "Tiny Home" designation if you have the pack. The skill gains are doubled, which means your toddlers and kids age up twice as fast. It’s basically a legal speedrun tactic.
- Focus on the "Independent" trait for toddlers. They can potty train themselves. This is not a suggestion; it is a survival requirement.
- Plant a garden immediately. Snapdragons and Lilies make for high-value flower arrangements or can just be sold raw for quick cash without leaving the lot.
The 100 baby challenge rules are designed to be grueling. They turn a life simulator into a high-stakes management game. Don't get discouraged when your first Matriarch passes out on the floor for the fifth time in a week. Just grab some coffee (for you and the Sim) and keep going.
