Writing skills

We bought a few writing exercise books from popular for Vernon to start learning his writing skills. And I found 123 or numbers is easier for them to pick up compare to alphabets. As I see Vernon use to join the alphabet by linking few lines instead of follow the normal writing sequence.

I decided to start from here, but I do face a problem where Vernon do not want me to hold his hand while writing. He always told me, no mommy.............Vernon write.....................

mommy only can watching and no holding. He very too Independence till we cannot disturb his capability or writing skills.
