DD will be 4 in July. She's under a paediatrician for speech delay and likely autism. She started nursery school in September and though it's an excellent school, she just isn't happy there. She likes the teachers and will occasionally chat to them but they struggle to understand her because of her poor speech. She has never had to be forced to go in crying or anything but her face lights up when she wakes and it's the weekend. She regularly asks not to go and has never said shes enjoyed anything she's done there. She has no friends and has never played with another child there.
I've arranged play dates with four different children from her class but there is no interaction from her at all. At parents evening her teacher said she plays alone in corners turned away from everyone else. She can share and take turns well with her siblings and will occasionally play with them. She has been off this week as she has an ear and chest infection and has barely been sleeping but despite illness, she has been massively happier than she is when she's at nursery school. She starts becoming withdrawn on Sunday evening and scratches and pinches herself until she bleeds when anxious 
I just don't feel she's gaining anything by being there and I know she would be a great deal happier at home. However, I also know she can't be a hermit for the rest of her life. Aibu to consider removing her or should she keep going in the hope it improves for her?
I'm a SAHM for the foreseeable future and planning to delay her entry to primary until 2017 anyway.
