You can create more than one Sim. This is a very good option - playing with a family or couple provides more fun and options. This page explains how to add new people to your family in The Sims 4, how to create relationships, and how to play with genes.
Adding more Sims
To add more Sims to the family, click the icon in the lower left corner. When you select "add a new Sim", creating them looks like creating any other Sim - you have to choose their traits, aspirations, appearance, clothes etc. There can be up to eight Sims in a family.
Editting the relationship
When you create at least two Sims, you'll be able to define the relationship between them, just click the button on the right side of voice selection. Depending on a situation and age, you can choose roommate, husband/wife (sex does not matter), brother/sister or father/mother.
Creating new Sims through genetics
When your two Sims are married or roommates, you can create their child with "play with genetics".
Choose "Child" on a pop-up list, then select two Sims below. Then choose sex and age (child or teen) and click "create son/daughter". You can modify the child, both in appearance and clothes. When it's done, choose their aspirations and traits and give them a name.
After creating a Sim, you can use genes to create their parent or siblings. The process is very similar to creating children, just choose another relations from the list.
When you finish creating the family, click the button in the lower right corner and accept in the pop-up window.
