Congratulations! Glad things are going well for you all!
One thing that comes to mind for teething: We had a mesh teether that you could put an ice cube, or frozen puree, or frozen breastmilk in and the baby couldn't swallow it. Something like this:
You could probably engineer a more permaculture-y version. Or even just a cloth with a knot dipped in water, or breast milk (and tied to a stick to prevent swallowing) and frozen.
Our daughter had a hard time teething and an ice cube really gave her a nice break from the discomfort enough to fall asleep. We also used acetaminophen suppositories as needed.
Another thing that helped us a lot. Our baby seemed to be very active and easily bored. She wanted to move around all the time and we couldn't keep up. Especially in the cold of winter, the house was boring, the car was boring (at the time, doctor visits and grocery shopping were an hour car ride each way) and she wasn't mobile enough to entertain herself yet. It worked well in our situation to get her a kindle tablet and make a playlist of interesting (to a baby) videos. This was her favorite:
When all else failed, we would bust out this video. The music is pretty mellow, but it can always be muted. The striking, high contrast visuals would snap her out of night terror crying, entertained her in the car, and made diaper changes easy. With the "blue shade" feature turned on at night, the screen color is shifted to red so the light doesn't wake you up.
I guess a more permaculture-y alternative to create striking visuals would be a kaleidoscope type thing over a light or maybe colored water and oil in a bottle that you shake up.
Last would be a swing. Our daughter loved to swing, still does.
