IF he likes typing than don't drop it. In today's world keyboarding skills are more important than writing.
And IMNSHO there is no reason for a five year old to be writing *anything*, except maybe his name. Work on those fine motor skills by coloring, cutting and pasting etc. There is also a curriculum, Ready Writer, that would help with this. It is basically pre-penmanship skills and consists of worksheets where the child traces lines, and it looks like fun.
