Jayta we did early enter DS into a public school - and we had a meeting with them at the end of last year prior to him starting. They were very supportive and open to acceleration etc eventhough they have never dealt with an exceptionally gifted child. He so far has somewhat been accelerated subject-wise but he isn't cooperating too much with the teacher and socially things really are not going too well. DS is really into strategy games and his teacher said he is very different to the other children, so academically and socially it really can't hurt to accelerate him. But we have run into some unexpected problems at school due to sensory issues and fears that he has. So really we are desperate to get this counselling going so we can make things better for him at school.
We have heard of a school that is good with gifted kids but DS has an older sister at his school already who is highly gifted - with a more uneven profile. But she has a couple of very good friendships at this school - and it will be very hard for me to have them at different schools (with getting them to and from school).
So I have to weigh up trying to make things work at this school for DS versus disrupting his older sister and making her move schools too. She already has anxiety issues so I really don't want to disrupt her.
Good luck with your decision to early enter or not - we really felt we had to send DS to school early as he was completely fed up with the boredom of preschool and "baby stuff".
