Yeah, I'm sure there are some mods that will allow children and teenagers, and possibly even babies to be Plant Sims. But I've never actually bothered to investigate the mods that will allow me to do this, or if I have the required mod already, if the Sim Transformer can do this. I haven't checked yet to see if it can.
