Mo - I used the term 'minor battle' because some of the little dears could be extremely stubborn on the subject - even when I tried your 'learning point'.
Unfortunately the education system in the UK insists that they should write their name using a capital for the first letter and then small letters. If they have been shown using nothing but capitals in the first place they have to 'unlearn' before writing it for the 'tick off sheets'!(and no I don't like those either).
Am I to suppose that you are happy with the idea of them not learning spellings or being allowed to write text speak on the grounds that it is their piece of work? It begins with being taught to write your name the 'right' way .......
