My DD has Selective mutism and Noonans syndrome. Last June we got her placed in a special school after a horrible 3 years at mainstream where the ripping behaviour started. She has to have old bits of tights all the time to rip when she needs them or she will rip holes in her clothes. A pair of cotton PJs last one night ,she starts on the seams and keeps poking and ripping until there is nothing left. She will poke and rip holes in jeans. She has started play therapy at school and some sensory OT work but no one has seen this kind of clothes ripping before. She has been referred to CAHMS 3 times over the last 6 years for her SM but they have never bothered to see her,far more urgent cases. She has severe separation anxiety and severe social anxiety(CAHMS can diagnose without ever meeting her) and have concerns about behaviour leading to self harm.Any one come across this before? Any suggestions welcome.
