DS has never liked writing - he was a slow starter due to not developing fine motor skills, and once he got going he really hated to do it. We backed off at home as it was causing huge fights and school told us he was doing ok in terms of progress - though normally the minimum required.
Now he is in Y3 there is a greater expectation to write more and also to consistently join. DS is now fairly regularly complaining that his hand hurts if he has to write a longer piece of work (fine with e.g. short answers to comprehension questions) and if he has to join more than a few words. At first I thought it was just a ploy to get out of writing, but am now wondering if it's more than that. His pencil grip looks ok to me (though I am obviously not a professional) - what else should I be looking at/helping with?
