DD is 6 & in Yr 1, she crosses her thumb over her pencil so sort of grips it in her fist. Teachers and us have been trying to correct it for two years but she will simply not do it. If you tell her she will hold it correctly but 10s later she's back to the original. Teacher says they do not agree with using triangle pencils or grips as they were advised not to do this by a physio when looking at another child (but not mine notably).
I'm not sure I agree as simply reminding and bribing is not working and I want to try something at home but don't know what. I've read other threads on here advising a range of things but wanted to know if anyone has had experience or success with anything in particular.
Thanks
