In case anyone hasn't found out, Live with Tribe! is somewhat buggy in how it detects your "completion" state. It seems to just check whether your inventory contains at least one coin and another item. If you just want to skip to the final impregnation-battle minigame, I've found that the least-effort method is to talk to the gate guard, fight the training dummy, talk to laundry girl and collect the laundry, go to the river with it (ideally no fights this and the next time), talk to the now-awake girl who tells you to go back to the river, do so the second time, and then skip straight to the chief with final inventory being 1 coin and 1 washed basket of laundry. This skips the dryad bossfight, every fight you'd have to do in forests 1-3, and the herb gathering quest.
Prior to this method I was using a more effort-required one of fighting the practice dummy, then going straight to the dryad at 2 for the rescue coin, then picking up a single piece of laundry to fill the inventory up enough for the chief to progress. Doing nothing but the practice dummy fight is a lot simpler though!
