Heavy work!!!! Totally! There are a lot of fidget toys you can get for school. my son uses a sit fit cushion in school, a wing nut pencil topper, all this to help him sit still. Weighted blankets, moving landscaping blocks in the yard, my yard is never put togehter because the blocks are all over the yard! lol small trampoline in house if you have room for it, get on your school about getting services if you haven't yet! Might be too over stim to sit still and the teacher wil need help to figure out ways to help him cope. My son goes into a quiet room for lunch because he gets migraines from al the noise in the cafeteria and being in class all day. Bands around the legs of the chair at school he can pull on, weighted lap pad, stuff like that! I was told I can say this, so I am, but I make the blankets and lap pads for next to nothing because it is ridiclous how much people charge for them, this is a desperate need for these kids and parents should not have to go poor to care for their child! So if you need help there let me know. THere are also pencil toppers that can go on that can be chewed on. GO and assess where he is sitting, maybe he is next to a yapper, or too close to the school bell by the door, florecent lights are a huge factor, have him put by the window for natural light. I will think of some other things! Welcome and you guys will be fine!!!!!!
