Sounds like she's both sensitive and a seeker. Tough combination. Not that any of them are easy as such, but still. The chewelry (or other chew toys) are a fantastic idea, and there are many relatively inexpensive versions that can be helpful. The swallowing is a problem. It's called oral defensiveness, and trying to make her eat things she can't swallow can only make things worse. It's hard to make nutrition work within those restriction, so you may have to be creative. Doing the chewing should help some. The therapy ball, trampoline, and any kind of crashing things (like big pillows she can fall on) or swings can also help. She will need to do them as much as she can every day, especially to start with. I think you will find that, once she gets more of the input she craves, she will find less need for self-stimulation. And while I know that is embarrassing, it is very common for seekers to use self-stimulation as the fastest way to get the input they need, besides biting their fingers or something similar (genitals and fingers are the most sensitive parts of the body, so quick input). You might be able to get her a fidget or something she can hold and fiddle with in her hands, especially for when she's in public. As for riding in the car, I have exactly the same problem. This is more related to her sensitivities. My coping includes wearing either ear plugs or in-the-ear ear buds with my mp3 player and good sunglasses. The ear plugs help both with my sound sensitivities and my vestibular sensitivities (your sense of balance), the music helps soothe my ears as well, and the glasses help my visual sensitivities. I cannot describe to you how much of a positive difference this has made in my driving experience. Plus, since I'm on a budget, it's important to me that this, also, is inexpensive. My mp3 player was only 35 dollars. The ear buds were 10 dollars (although more comfortable ones can get pricey), and the sunglasses can be even cheaper. And I feel sure that other people can give some even better suggestions, but I figured I'd give you a start. I'm so glad that you are giving her a chance to help you choose things like what she will chew. I hope that this will open up some dialogue in your family that will make things smoother for everyone.

Thank you so much for sharing this with us. I know it's scary to admit things like you did with no expectation of how people will respond. It's a brave and ultimately good thing to help us understand and, hopefully, help you get some better advice. I hope for the best for you and your family!
