DS is in reception. Last week they introduced 'tasks' to the children that they must complete, I suppose to ease them into doing actual work. The task that day was to cut things out. DS really struggles with scissors - something we've been trying to help at home but he's just not getting it just yet.
He didn't want to do the task set because of the cutting, and I don't know the exact details but he apparently refused and was given a couple of chances, before his name was moved down a notch (they have a traffic light system). He then did the task with a TA's help. It was the first time his name had been moved, he told me he was crying while he was doing his task and he was all alone, because the other children had moved on to something else
He came out of school that day in floods of tears and the teacher told me what had happened.
I thought well, that's really quite sad, but hopefully he'll know now that he has to do the task set by the teacher and hopefully there won't be a problem again.
Only it's been a week now and despite constant reassurances from me he's still really, really upset.
He'll randomnly burst into tears when he thinks about it and it's made him really anxious about the jobs the teacher might give him. He's waking at night upset about it and saying he doesn't want to go to school anymore 
I had a word with the teacher today and she said she'll talk to him but I'm not sure if it'll help. I've never seen him so anxious. What can I do?
