How many kids do you prefer to have per couple?

I used to let nature take its course but with Seasons and the extra activities, I am limiting my offspring to two babies per household. With Seasons and Parenthood, it takes a lot more effort to raise kids. And I use the in-game cheats for one boy and one girl per household. I know, I'm a micromanager. Guilty as charged. I like to keep my worlds balanced so there is less effort in finding suitable spouses.
