Muslims are not required to fast until they reach puberty, and these were aged 10? Many children do, they do a half fast so they can get into the habit, and it makes them feel like they're taking part in the "grown ups family activity"

So in other words, if any were fasting, it was their choice.

The fast by the way, nothing is allowed to pass the lips - they don't drink or eat anything. We have a Ramadan calendar pinned up at work, and at the moment that means from about half 2 in the morning until about half 9 at night. That must be hard in this weather, but apparently that's the idea - to suffer and know what the poor feel like.
