Ds has a nervous/comfort thing where he puts his hands together and twists them into different shapes. He does it when he's nervous/anxious/bored. The last two days he's been upset after school and it turns out that his one-to-one and another TA have been onto him to "stop the hand thing". I don't know why they think it's something he can just stop at will? Would you speak to the teacher/senco/TA? I'm always nervous about confronting the one to one because I want a good relationship with her.
