How often do you create families and households that have multiple sims?

I notice most of my households tend to be couples or couples with a toddler or child. I love family play and just want to dive into the parenthood aspect. A few times I had a few couples, or single parents, but I rarely have single sims households.

(I’m a rotational player. I usually play with Aging Off, and then age the younger sims when I feel like it.)
