A very basic Mount & Blade 2: Bannerlord mod that does will do two things:

• displays a count of your children in the bottom right map bar so you can be a proud parent
• provides a baby vending machine if for reasons your spouse (or self) are not getting pregnant or delivering babies

Essentially I had the second problem and rather than wait for a patch, decided to nuke it from orbit by learning how to do Bannerlord mods. It's the only way to be sure.

Bonus though, it's a reasonably simple example project if you want to start modifying the Bannerlord UI with UIExtenderEx.

• Bannerlord.Harmony
• Bannerlord.UIExtenderEx

Build and install manually. Nexus/Vortex might come later, idk. Harmony comes first, then UIExtenderEx, then everything else, then this.

Save. Press butan. Get baby. Profit.
