Ds started mainstream reception in September. I was worried about mainstream suitability but told ds was too bright for a statement so see what happens (have to fail first). First half term looked ok - hardly any feedback from school but ds seemed positive and appeared to be learning.
Since returning after half term he has become withdrawn, has increased tantrums massively and is back to aggressive behaviour at home. Ds has also picked up a new obsession and is scared to be on his own (even going to the toilet is a family outing now). What is worrying us most is our very excitable and energetic ds is now choosing to sit next to the teacher all the time (the rest of the class spend most of the day roaming the classroom in free flow play). Teacher does not think there is any problem but TA does. Need advice on what to do next. I feel so guilty for having put him in a situation he cannot cope with.
