DS (3.11 ,asd) has got this habit of wrapping himself with pieces of elastic , strings, trousers belt,... a sensory thing i believe.
He likes the feeling of it obviously. He wraps his fingers and hands, arms, or chest usually, a couple of times i caught him with elastic straps (from ds1 bedroom), wrapped around his neck, once he had looped one around door handle and popped his head within the loop and was moving back and forth so that the elastic would catch on his neck
Anyway, yesterday we went to get a new pair of glasses for him (he now has to wear them but of course refuses to), and he was given a helium ballon on a string. He wanted it attached to his wrist so we obliged.
He was quite happy carrying the ballon like this for the rest of the day. Then we were watching a bit of tv when we heard a gaging sort of noise, we turned to DS who was sitting at his little table and he had wrapped the string around his neck. His face was turning purple and his eyes were bulging out, how scary!
DS1 (16y) was closest, jumped to loosen the string.
We took it off quick. And DS just sat there as if nothing had happened!!! WTH???
He was making a lot of throat noises so i called NHS direct to ask for advice.
We usually hide all strings , elastic, belts,... as he will hunt for them and has the nack of finding stuff like that.
Just didn't think he would try it with the ballon string...how silly of us!
