We know now that fidgeting can help with focus and calming yourself (or your child) down. When I’m on the phone, I simply cannot focus on the conversation. In the old days, I’d play with a paperclip (and end up stabbing myself, usually), but now there are tons of fidget toys out there. Now I use something similar to the mesh squishy ball and find that I can sit longer and not drift off into space while on the phone.
