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

I always start a new save with one Sim Rags to Riches style unless I'm playing a challenge that requires more. I like to keep my households small, so those single Sims might find love and get married. If they have children, it's two max, or three if the second 'try for baby' ends up twins. I've only had triplets once in all the years I've played Sims and that was my very first babies when I did the 100 Baby Challenge. Talk about starting out on a high note! hehe Or low, depending on how you feel about raising multiples. :D
