When other NPCs are aging normally, it is possible for Sims 4 players to keep their characters from aging, as follows:

The first option in the game: Will the villain you control get old? There are two options.

The second option in the game: Will other neighbors get old?

Players can choose the corresponding mode they want through these two options.

Or buy a bottle of 1500 in the reward shop, which can clear the warehouse at the current age, that is, you can always stay young.

But players want to keep their villains from getting old, and as a result, a bunch of children born don't grow up.

But there is a way: just make a chocolate cake, then choose what candles to put in the cake, make a wish, and you can grow up or get old directly (suitable for players who turn off the aging option and expect their daughters to grow up).

But if you want your son to grow up, there is no other way but to grow old. Therefore, the above settings should be used with caution.

Another way:

You can use the mc center to adjust the length of time at each age stage. Recommended adjustment method: two days for the baby, seven days for the child and twelve days for the child, and all others are 1000 days.

If you want to keep yourself and your neighbors from getting old, you can always drink aphrodisiac, so that your neighbors won't die of old age.
