All sarcasm aside, my guess is that there's a limited amount FAs can do in this situation. I'd be surprised if they can physically restrain the child except in extreme circumstances. So the most they can do may be limited to chastising the parents. Maybe they didn't even do that in this case, but I don't know that they truly can force compliance with the rules.
Maybe one of our FA friends can help us out here.
