When to start cursive writing

[readingmakesmehappy]

DS has just moved from a school which only taught cursive writing from Reception. All of their writing from the very start was cursive. I went with it because I didn't know any better but I increasingly think it was an insane policy. It is a huge battle to get him (now in Yr 1) to do any writing, because I think he finds it so difficult to form the letters with all the joins etc.
I would be interested in other posters' thoughts.

It does depend on the child's manual dexterity, I think, but start as you mean to go on: letters should be taught with joining points and proper ascenders and descenders. Nothing is worse than bubble writing!
