I have a 4 year old daughter who has had speech therapy since 2 years old, she started nursery aged 2 and a half, and the nursery were very concerned, her eye contact was very limited, she acted as if other children were not present, she could not understand what was being asked of her, she walked on her toes, her concentration was appaling, and she has to have a rountine, she can not cope with change at all. e.g. if at nursery, she will take off her dressing up clothes and leave them on the chair, to wash her hands, if she has to wash her hands first she can not seem to be able to cope or if her dress up clothes get moved off of the chair.she is so clever she can clearly write, count, recognize shapes numbers up to 50. She is a very difficult child but is very loving, and always reaching out for reassurance.She has had 1 to 1 key worker throughout her 2 years at nursery she is now due to start school and a 1 to 1 helper has been arranged. She is on school action plus and is classed at having special eductaional needs but She has never been diagnosed with autism, and i do think she has it mildly. My 2 year old is now starting to look the same way, he barely speaks and can not seem to understand my commands, although his behaviour is alot better than my daughters at this age i am starting to worry that he to could be autistic. i also have a 7 year old who was the exact opposite, she is very advanced and is getting on brilliantly at school.
