sims 4 I can’t add another parent in CAS [ Edited ]

Are you trying to add a connection of sims in the household already, (?) I get that but your picture is showing the child, you have to click on the adults and make the correct connection there: via the adults, not the child, ie: connect the adults first

Ok @Bee9908 another try for you, this was from a few questions of yours back in the thread.

• "They are not siblings or cousins. Both are married couples. It is possible for them to get pregnant by “try for baby” interaction, but I cannot add kids in CAS, I can only create a kid of one of my sims."

So, simply click on the + sign not 'play with genetics' all the time, just 'add a sim' - family association afterwards: with the plus sign (on the right of the sims) or adding from gallery and merging is the normal / easy way to add to a family
