nononsensenanny - no-one is being nasty or inflammatory - the OP asked whether we thought she was being unreasonable, some people think she is. If she didn't want opinions, why post?
What we are reacting to, is the idea that a supposed caring professional is sitting by while a child in her care cries for hours on end (she mentioned on her other thread that she was sitting beside him mning while he was in tears in his highchair), and her main reaction is to worry about her own children, rather than try to get to the bottom of what is bothering this poor little chap.
As for your other post - words fail me. Yes, he is three, yes he has other ways to communicate, so why isn't he using them? Why does he feel crying is the only method that will be listened to? There is a REASON children communicate in a certain way and that reason is rarely innate naughtiness, it may be boredom, frustration or real sadness, but no-where in the OP does Ofsted express any desire to understand what's in the child's mind, her only dilemma is whether to give notice or not.
I think many people have responded with sadness because we think of how we would want our own children to be responded to if they were crying with frustration. If my 3 yo DS, for whatever reason, were crying for hours at nursery, I would be devastated to find his keyworker hadn't bothered to discuss the situation with me and was in fact wondering if/how to get rid. And yes, in that situation, I would think the nursery was being bloody unreasonable.
And btw I have read the other thread (on childcare) and I don't think it's entirely fair to say the responses were entirely the opposite. The majority of people there, like here, advised you to try to get to the bottom of the situation and have a heart to heart with the mother.
