Hi,Im not gonna say dnt worry cause its what we all do. Heres my story and take on your worries.
My 4 and half ds,started the schools pre school in the morning last year,to me a normal,active,strongwilled and shy boy.
After being at the school only one term. We we alerted by the teacher to him showing the same traits as your daughter. most the same apart from he didnt want to play with others. He liked his own games and had his own friends out of school. they mentioned all the above as they did with your daughter but also asd.
So as you can guess the worrys majorly set in.
now nearly at the end of the journey through apppointments after appiontments after appointments. Seeing so many people with diff views on my ds. Still other appointments and assesments to come.
they all so far have come to the same conclusion as what we his parents always belived.
He is bloody fine!! and only still nearly 5years old!
she is still only very young herself.
It takes me telling my partner who is 32 at least 4 times to do what i asked him,so I wouldnt worry at this.
Fidgeting i dont belive ever stops untill their lazy teenagers! I still fidget and bet you do too.
Too me,i found that the schools are afriad of missing thing with our kids now that they can jump on the tinyest problem,so they dont miss it.
But if there is a problem the sonner you get the right advice and put it into practice,the easier(i found)it was to understand.
And also once i admitted that my ds could be a little sod,that i spoilt him,lazy and unwilling when things wernt what he wanted or his way and needed me to be a lot firmer and yes! he can be naughty,things are getting easier to understand.
Reading your post your dd,sounds like bright,imagantive little girl and that is what you want.
Not sure how this helps at all but thought a read through it will help.
