My son has started school this year. We are working parents and spend less time with him. Most of the time he is with nanny who speaks different language. So he is behind in speech and language. His behavior is very different at home and in school. He is a perfectly happy and healthy child ate home. Now school is trying to prove that he is autistic which he is definitely not. He like to play alone and doesn't like orders. It seems that they are trying to get rid of him. He is last July born and youngest in his class. I have seen significant improvement in him since he started school. Can they throw him out of school without our consent. what options do we have.
