If he has a written statement of needs and the kindy has that, you do nothing. Liebs does not and will not have this, so I flag it up for his teachers atm.

TBH, I see so many children with communication differences these days that I can spot it fairly quickly. As do others. Children don't need statements but do need caring adults, differences or not. And teachers do talk to each other.

I'd flag it even if I didn't need to, just for peace of mind. And I don't mind parents flagging me with stuff I have buried under 5000 other similar pieces of paper (also stored on computer and annotated on registers and my seating plans and lesson plans - not ignored, I promise).
