i have put a container of "fiddlies" as DS calls them together for when we go out in the car or to somewhere that makes him feel anxious.
In a plastic tupperware pot is :
An assortment of coloured elastic bands
A key ring
A little chain
sparkly wool
little mini pen
It keeps him occupied, he sits for ages twiddling and i must admit that i pinch some of his stuff for me!!!!
