hi there,just joined mumsnet as im seem to be sendind myself slighty crazy with worry! since my 4yr boy started foundation stage 1 he is showing signs of asd?? we are just waitng for the app with the education pyhcologist(sorry bout the spelling). He seems to be really struggling socially at school and within big groups once the door shuts.He plays happly with the big groups when im stood there.It seems to have just popped out of nowhere. And am now worrying as he returns back to school for full days shorlty. he seems to be completley unaware of it all and loves school,learning. Im just completely at a blank with. thanks
