My daughter is 8 and it has only been within the last year (specifically, finding THIS website) that I have discovered answers to all the "annoying" and "picky" things that she has fussed about or done in her life. She has SPD! Go figure!! While we are working on finding what works best for her, I have discovered that she likes two items which are very simple to make at home: a rice bin or a bean bin. We made one of each. Find a large container with a lid and fill it with rice or any type of dried beans. Then add little fidget items or small treasures like a marble, large paperclip, big button, pencil eraser, a set of dice, a quarter, etc. My daughter plunges both hands into the bin or bucket and allows the rice or beans to flow over her hands, over and over again. Sometimes she digs for the little treasures until she finds them all. Other times, she's just in the bucket for the feel of it. Either way, she will play for 20 minutes or more in these and they seem to calm her.
