Hello! New modder here. I'm looking to make a mod that I know heaps of people have been wanting-- a grown up children mod. Like getting rid of those annoying toddlers and replacing them with teens or children who could have had development and personalities and maybe help around the farm. It could be similar to the happy birthday mod where at the start of the game you pick the personality for your child, like that kind of menu. Anyway, ideas aside, I know that it would probably have to be a SMAPI mod. I know that some people have made custom NPC mods, but I don't know where to start. Can anyone please help me? Thank you!
