Look i know that there is like a million of these but maybethe kids could grow up like animals and help with the farm like junimos. Also maybe you could put your children up for adoption to randomly appear with other npcs. May also be able to change appearance at shrine of illusions. Comment more ideas
I know it's just a videogame, but the impulse to breed so you have farm help is an ugly one IRL, historically. One which that I, for one, would hate to see replicated, however obliquely. I suspect that just about anyone whose parents had them help run a small family business can relate.
I guess, but the children do absolutely nothing except get in your way. And it would be absolutely absurd if you milked your children!
If kids would help when they are teenagers (a bit) it would be okay. You know, like "Hey mom, I watered your crops today !", kind of like your spouse .
