Article on 'Growing up fast' here
I related a lot to the argument she makes about the choice to defer entry for a term or so for summer-born children being a false choice. The school and council wouldn't even tell us how many other children were deferring and just kept reiterating that it was up to us, but she would probably find it difficult to make friends if we didn't start her with all the others in September. We came under immense pressure to start her in September. Also (as the article says) if all the other children leave pre-school, there is little point staying on and being so much older than the others.
Some of the parents wanted to do part-time days to start their (summer-born) children off with a gradual introduction to school, but the authorities said it wasn't fair for local taxpayers who had paid for whole days! (!!!)
