My DS is 4 and has just started school. We have thought that potentially he may need extra support and potentially have some form of neurodiversity for a while. His teacher has raised this as well. Where is the best place to start? I have left a message for the HV as he is under 5 but I’m not sure what I expect them to do. From what we have read we were thinking he may have autism. What might a diagnosis help with at his age and as he goes through school?
