I used to get a little annoyed when my characters in vanilla would just not stop having kids but then I played Lux Invicta where they nerfed the hell out of child survival rates and fertility.

I think performance issues were also mentioned- everybody having several kids that die young and do nothing would be a drain on performance for little benefit. IIRC Paradox said that the reason CKII doesn't simulate the low child life expectancy of the era is that they found it just too depressing, so they chose to balance it out by lowering the birthrate from the historical levels.
