How many kids do you prefer to have per couple?

I can’t just particularly give a number but thinking of my long time 4 generation save, its either 2 or 4. But generally only two at a time. First gen had two then when the eldest moved out they had a third, so two at a time. The eldest had twins and when the twins moved out had another two (although aged apart). There was also a step-brother but he was old and moved out quickly. By third gen all cousins and family had an average of 2-3 kids with the sim I was playing having twins when I really just wanted one and so she ended up with three kids and had to raise her husbands illegitimate child. So 4. Illegitimate child moved out, had a mistake baby and a baby through surrogate. I intend for her to have two more but when those first two are old. So really it’s often two at a time. I guess.
