Long story, have been on and off this board and you have all been so helpful.
My DS is struggling at school, and after a long time (from yr1 to currently yr5) he is on the verge of being dismissed from the community paed. Team. She has acknowledged his sensory issues. He has been discharged from SALT after 2 very short assessments (? Social communication issue) and grudglingly gave him Melatonin for sleep (that has been a revelation!)
So anyway. I have done everything I could to help him and have failed. I have been dismissed as an over-anxious mother with a child with sensory issues, tics and quirks. Apparently he will be fine. Which is nice.
School continue to be helpful, and acknowledge his problems with sensory and social communication.
So I guess it's time to pretend everything is fine. Thank you all for the wise words, and the best of luck with your DC.
