Sims with certain traits might start with some positive or negative values by default. That'd be average in The Sims 4 Parenthood. It's possible to age up and get nothing special if the Sim remains neutral. Since this is somewhat of a leveling system, you would have more time to have a positive (or negative) influence if you raised a child from toddler to adult assuming all goes well. Those who enforce no discipline may get a child who is irresponsible or argumentative. Players who have babies and raise them to be good will see those children get useful traits such as responsible or mediator. Youth is a time of changing behavior, thus there is time to correct bad behavior and reinforce good behavior to get a trait you want, or avoid one that you do not. This applies as long as those values are maintained or go uncorrected, anyway. When a Sim reaches the extreme at either end of the spectrum, around 90%, they will get one of two traits for that category upon aging up to Young Adult.

These values begin at a neutral level and can go into the positive, but also into the negative. Youthful Sims can gain or lose points in one of five categories, based upon their own behaviors and how their parent reacts to their behavior. Discipline the negatives your child develops, and praise the positives to help them avoid bad traits. How it Works A 'Teachable Moment' chance card often has a positive and negative outcome. Parenting Skill - The new skill that helps your Sims improve as parents.Parenthood DLC - An Overview of the DLC.

Some Simmers may wish to play parent to young Sims and leave them autonomous, hoping to get a good outcome.

There's a strong tie-in to the Parenting skill, but this gameplay system stands on its own because the youth's actions alone can impact their values. Upon aging up to adult, these values may result in a permanent trait that accompanies the regular traits you choose for your Sims. As Sims grow into adults, events, actions, and day to day responsibilities will gradually improve or decline one of five core values. The Sims 4 Parenthood Game Pack's core feature is a character values system that effects Sims from the toddler life stage up through teen.
