I love my DS2 and his quirks with all of my heart but he has just developed a new finger clicking stim and I don't know why as he's had noisy ones before but this particular one is grating on EVERY nerve I have left. It's really incessant, sometimes in a pattern, sometimes random and I KNOW he cant help it/is barely aware he's even doing it but arrgghhhh! Any advice please before I rip my own ears off?
