Hi we are in the same situation as you are daughter who is 3 has been told by the paediatrician that he thinks she is autistic but could be a full year before we get a full diagnosis but they are hoping things might improve I have spoken to school and am seeing special needs coordinator after Easter
Hopefully it doesn't take a year! It can be stressful just waiting when deep down you know, but you'll get there it's a good thing the school's aware of it all, don't know what i would of done without the support worker from ours!
Keep me posted on how it goes
All the best x
