Hi! I'm so glad that you found us. I hope that we can give you a home where you can get some support for what you need.
Maybe we can figure some things out together.
From the little you told us about what your daughter is like, it sounds like she is a sensory seeker. It will help us a lot to make suggestions if you can tell us more about how her SPD manifests, since there are, as you said, different kinds. That said, if she is a sensory seeker, I think you will find it helpful to get her things that help her safely get that input. A therapy ball to bounce and roll on would be good, and they are not very expensive. A small trampoline would also be helpful. A lot of seekers also like to be smashed, so big hugs, pushing on them while they're lying down, things of that nature can be incredibly relaxing and comfortable for them. Giving them a chance to get input that puts pressure on them and pressure on their joints is very helpful.
At least, that would be a good start. Plus, that joint pressure is also quite helpful for just about anyone with SPD.
It sounds like you have a busy, happy home.
I've thought of homeschooling myself, but I'm not sure I'm brave enough.
I am very interested to hear how you do things. In keeping teaching in mind, I was thinking about what you could tell your kids about your daughter, and only one thing came to mind. I think I would suggest starting the conversation by talking about how everyone sees and feels things differently, and then I would tell them that her brain makes her see, hear, so on, louder (or softer, if she's an undersensitive) than other people, and that's why she does things they don't understand. Put in some examples, and I think it'll make sense to them. Frankly, that's exactly how I explained it to my husband. New examples and such as time goes on will eventually integrate it into their understanding. Even my husband is still sometimes surprised when I point out something that is effected by my SPD, but at least its more of a, oh, that makes better sense, than a do what?!
Anyway, we would love to hear more from you. Glad you came by, and look forward to hearing from you more!
Gack! I forgot I wanted to say, if you want to put a lesson on how the brain works in there, you could tell them the theory about how everything is filtered by the lower brain stem first for danger before your thinking brain gets a chance at it, which is why people can't "think" themselves out of automatic startle reactions when they have SPD (if she's oversensitive). Just a thought.
