I'm pretty sure that the petit miam baby yoghurt doesn't have any added sugar. They also do something to it to make it easier to digest that adult yoghurts - add more of the easily digested milk protein and less of the other harder to digest one I think. I kept Kynan on the petit miam baby yoghurts until recently as he didn't like natural yoghurt even with fruit added but in the last couple of weeks I've discovered the Tamar Valley yoghurts which Kynan loves. It's natural yoghurt with fruit already added but no sugar.
