My ds has some undiagnosed need - we are restarting an assessment process and he has a long history of Sensory difficulties, feeding difficulties, transitional difficulties, etc. At any rate, he has recently begun a new behavior/stim/self comfort of pulling up his sleeve and sucking/biting on his arm until the area is quite red. He says he needs to do it to calm himself. He is open to suggestions to change self calming behaviours or stim behaviors to ones that are less destructive/harmful (such as when I introduced the use of a hammock to use when he was having a full body tantrum. He now can put himself in it or ask me to help get into it as the meltdown is amping up and will stay there until he calms down). Can anyone suggest a substitute behavior that will suffice for biting/sucking that might be calming? I can't think of any at the moment and need to come up with something before he hurts himself!
Thank you :-)
