unstructured time can be difficult for those who find social skills difficult. I hope it is a blip and the school reply soon.
Do the school have anywhere other than the library DD could go? Some of the schools I have looked at for DS2&3 have a room staffed by learning support or pastoral staff. It is a place to get away for the hustle and bustle of the rest of the school, but also a place to develop social skills with staff support. Or are there any extra curricular clubs she could go to?
Welcome Big. You won't hear "children are resilient" or "it will get better" from me, they are two phrases I loath. Some of the things that have helped here are visual timetables, now and next boards, a strict routine, ear defenders/noise cancelling headphones, emotions cards. For a while I kept a detailed diary to spot triggers.
Has your DS had ELSA input? This is a big one for us, how can DS tell you how he feels if he doesn't know a) what he feels and b) what each emotion is. OT and SALT are other big ones.
A worry book, social stories and role play haven't helped us, but you may find them useful.
I second CAMHS if not already under them. Also, do the school run a rainbows intervention group?
Zoo pressure the LAs well, it is them that is responsible for providing him an education.
DS1 has been grumpy and anxious all day, the smallest thing set him off.
