More Babies For Counts & Dukes
Counts and Dukes, and their unlanded children, will now have more babies. In a time of death by combat, disease, and maternal mortality, lineages at the feudal foundations will no longer be hamstrung by fertility nerfs.
Counts and their unlanded sons and daughters will now have a base of 4 children, up from 2, and Dukes and their unlanded sons and daughters will now have a base of 5 children, up from 3. Rulers get a vanilla bonus of 2 children, and there is a vanilla 50% chance a couple will have 1 less child.
Overall ruling Counts will now have a base of 5 to 6 children, and ruling Dukes will have a base of 6 to 7 children, in line with the vanilla base for ruling Kings and Emperors of 6 to 7 children.
The feudal foundations will now be better positioned to pass on titles from generation to generation, produce more men and women for other characters to marry, and contest titles through war and marriage rather than by lineage extinction.
Partition on succession may become harder as more heirs will exist to inherit. There may be a performance cost as more characters fill the game world, although I haven’t noticed any in my playtesting.
Another effect is likely to be less female rulers of counties and dukedoms as more of their brothers will exist to survive their landed parents and inherit their titles.
Works Well With

Imposes marriage opinion penalties and hard nerfs on older and infertile women. The AI will no longer marry their teenage heirs to 60 year old grannies. Fertility and age become top matchmaking criteria and the AI will search wider and deeper on the map for the right young woman to bear their legitimate children in the longest reproductive window.
