9 year old DS has always has issues with fine motor skills and in turn his handwriting. He's working hard at homeschooling but with much of the work being online, his handwriting is really slipping, to the point where I'm sitting with him constantly encouraging him to stay on the line, take his time etc. I really dont want to produce babyish letter forming sheets that his 6yo brother is coming to the end of. Any ideas? He seems to tire of writing easily, he uses a thick pencil and has always formed his letters in awkward ways. Teachers haven't seemed too concerned except for a referral to physio where he was discharged after assessment, but its becoming such an issue that a lot of it is nearly unreadable.
