I have been very spoilt living here in the US ,it is a piece of cake to defer a year or hold your child back if you and the school want to ...
Why is it such a pita to do it in the UK ?
I want to do it for my August born son when we return in the Autumn ,he only started school in 2009 (at 6) and when we come home he needs to go to year 4 !
I understand this particular part only pertains to me ,but there are so many parents who want to start their summer born kids later ~I think they should be allowed to with zero fuss .
Now that school/training is going to be gradually introduced till 18 ,surely we should have more flexibility to do what we want for our children 
Obviously ,those that would like their children to start in the present system should be given that option also .
I have spoken to the Primary school my son will attend ,and although they are not ruling out holding him back ,it would only be a temporary measure ?
I want it for good ...I personally want more choice ...
Unreasonable ?
