We were struggling a lot with our son for creative writing and made him join a crash course too in August. It didn't help much, on the other had put a lot of pressure on him. Please check this book, we found it very useful. He started enjoying it more as he had some interesting openings/phrases etc to use.http://www.amazon.co.uk/Descriptosaurus ... iptosaurus
I used to encourage him to write just few lines first, then we moved on to writing few paragraphs and after a year he can write a 2 page story with less resistance.
