DS (5.8) is just about to be diagnosed with Pervasive Developmental Disorder. We currently live in Spain where he was born. He has never really picked up Spanish and the diagnosis process has been helped by the fact that the doctor trained in London. He will get help at school but we are seriously considering moving back the UK to help his development and education. In the meantime he appears to be perfectly happy here. We are all British so there would be no problems coming back but from anyone's experience is this a good idea. I feel like we would need lots of time to prepare and get the right school.
