How many kids do you prefer to have per couple?

I went with two. If I'm straight up playing a couple together it probably averages out to two. I've been playing the same group of sims for the longest time. I can think of one couple that had 3 children together (one was an alien abduction but ya know). I have another sim that had 3 children with 3 different fathers but her oldest died right after turning YA. A lot of times I'm happy enough having my couples have one child. Otherwise, I feel like I can't focus on everyone.
