Two parents.
One AI baby.
A hundred days.

Day to day
Small chores, every day.
Hunger, cleanliness and mood all run down over time. You feed it, bathe it and pat its head, and some of those have cooldowns. You can't do it all in one go.
Feed
Hunger goes down while you're away. Feed it from what you've cooked.
Bathe
Cleanliness goes down too. Bath time fixes that.
Pat its head
Good for mood. There's a cooldown, so you can't spam it.
Tantrums
When it has a meltdown, both parents have to comfort it. One parent alone can't calm it down.
The world
It goes out. It comes back with things.
Adventures
Send the baby out for hours at a time. It brings back ingredients, building materials and the odd rare find.
Cook
Turn what it brings home into recipes.

Build & garden
Make furniture for its room, then work on the yard: flower pots, a swing, a lantern. Plants need watering over several days.
Stories
Things happen. Some of them take a while.
Growth periods
Rebellious, playful, puberty… Each phase only ends when you find the right item for it.
?A mysterious purple egg
Found in a crack between the rocks. Still warm. Nobody knows what's inside.
Day 100
The story stops on its best day.
On day 100 the game ends. There's no goodbye. The story freezes on the baby's best day, and the family stays together for good. You can export the diary and keep all hundred days.
