My son has had quite the journey regarding writing challenges ever since Kindergarten. He was identified as gifted, but also earmarked for needing occupational therapy (OT) for handwriting. So in 1st grade, he went to a gifted program and had 1:1 instruction to try to correct his fine-motor issues.
I have a genetic nerve disorder, and perhaps my son is not entirely in the clear. However a neurologist didn't find anything in particular wrong, and so the OT continued until 7th grade.
Due to his continuing difficulty with writing, my son avoided writing like the plague.
