Son is 3 and being assessed for autism. Told it's likely he will be diagnosed and that they're also considering ADHD. He very obviously has both. I have fairly "bad" ADHD myself so I know exactly what it is.
Recently he's been having major meltdowns and outbursts of aggression at nursery. Throwing things, biting, kicking etc. He's speech delayed so can't communicate properly and often the other, older and more articulate children talk over him. The staffing ratio is 1 to 8 which is crap, I have barely any of these issues at home because I can see and intervene before we get to meltdown but they have too many children to do that.
Anyway my son is doing this because he is anxious. I nearly died and spent a lot of time in hospital and this is when his behaviour suddenly went like this. He keeps telling me he is scared I will leave him
I have told him he can speak to me whenever he wants and asked nursery to call me if he is distressed and let me talk him down. Firstly they told me no because it'll upset the other children, I said I think getting bitten will upset them more. Then they said the office phone is always too busy so they don't want him getting upset over not being able to use the phone.
I offered to buy a mobile phone and give to his key worker and that only I have the number to, and that they can tell him is a phone to mummy and to use that.
Got told no as that would take the key worker away from other children. I said but you're already away from them by spending half an hour calming his meltdowns down!
Asked if I could keep it in the office and one of the admin ladies could call me from it and supervise. Told no as their admin work is very important 
This isn't fair is it?! They should be making reasonable adjustments.
