Hi, I'm courious about this. We think my DD16 in addition to her GDD she is suffering from Selective Mutism. We were thinking of this as a possible option prior to start of her rage attacks last November. Did the LLMD provide a starting place?
I haven't been exposed to CBT but maked some assumptions. What I started doing with DD16 is when I realise the onset of her patterns I try to get her to change her thoughts. Usually just by getting her to laugh and playing around, anyhing really just to occupy her brain with something else. I have no real clue as to what I'm doing but it seems to have an effect. If I leave her be, it often develops into a meltdown or extreme mood swings.
