Thanks for all your replies,

I ended up calling the school and they said that she can do what they call the transition period where she can go for 4 weeks and if they think that she isn't ready then i can start her next year.

She started last Thursday and was very excited and keen and when i left her she was absolutely fine. the teacher said she is coping really well so far, following direction and being involved in all activities. She even got up early this morning asking if she is going to school.

So i feel better that she doesn't have to stay all year if she isn't ready and like astrolady said, i can really see it making a difference in her already after only 2 days, she is coming out of her shell.
