Thank you Stroller and Bob1892 for your thoughts.
I wholeheartedly believe that it can be done without a tutor but not without some sort of tuition/coaching/preparing etc from parents/family. After all NVR is not taught at my sons primary school and if children have not seen this sort of thing before it will most definitely throw them out!
General consensus between parents i have spoken to is that they send their children to a tutor purely because other people do and they feel that they only have one shot at this so they want to ensure they get it right.....i understand this as you don't get a second chance so of course you want to give your DC the best chance.
This is my second journey so i am going to go for it.
All i can say it's going to be a bumpy ride..... and a roller coaster of emotions.
..... Good Luck and best wishes to all.
