DS1 is 3.5 dx ASD.
He's been at his current preschool since October and settled immediately, looked forward to going, constantly asked to go etc etc. (he had been at another one which was completely disastrous). He goes 2 sessions a week.
In January he started at a development nursery again for 2 sessions a week. It's run by 2 experienced nursery nurses and there was originally 4 other children and now there are just 2. His placement there will finish at Easter.
About a month ago he started crying at his preschool and he has become progressively more clingy and upset about going there and me leaving him. I found out his keyworker was due to leave so all the other staff there had been approaching DS1 rather than just his keyworker and the manager. His keyworker has now left and he doesn't have another one yet. I've been told he is absolutely fine once I have gone.
He is also upset and anxious about me leaving him at nursery but not as much. The nursery nurse says he plays well but constantly runs up to give her a cuddle and needs lots of reassurance.
It's spilling over into home now, he spends a lot of time being upset, constantly needing cuddles, saying he is scared of various things (food, the wind, me?, books, tv, toys etc) and his tantrums are ever increasing.
The most I can get out of him is that when he is at preschool he just wants to go home. He never asks for anything he needs there (toilet, drink, top zipping up etc) and I just don't know how to tackle it as on the face of it he will look fine but in reality he is storing it all up for when I collect him and the afternoons are just miserable right-offs.
Any suggestions on what I can do to reverse this situation?
