At this stage we plan to start DS at 4yrs9mths as he makes the cut off by 7 days and has happily been in childcare since he was 15 months for a couple of days a week. He'll start in 2014. At this stage we are pretty comfortable as he is a social child who is cluey and already doing the kindy program at childcare so can already spell and do a lot of reception year activities. However if at age 4.5 we see signs that indicate he is not ready then we can change our mind and hold him back.

WYSIWYG - I'd be interested in the UK reasons too, especially as DS will be 4 we he starts
