I don't do everything every day or even every week! And some of these themes are only basically touched on. For example, for farm animals, I just read some books we have and took out from the library, I put out our barn and farm animal toys, and I planned it for when we normally go to the county fair. If you want more info on how I fit everything in, I have a lot more information in my routine video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2bBKVWp-gKg.html
One of the wonderful things about it is you can adapt it to a variety of ages! So at 2.5/3 it is more inspiration for you - but there is no reason you couldn't look for the specific things on nature walks, read some of the picture books, and do some easy art with them! I have used it from preschool on up into elementary.
