Small kids dont get drunk, and generally aren't rude to the FAs. Give me badly behaved kids over yobbish parents ANYDAY.
Once on long haul, Senior Management and myself had a young baby in front of us, yelling the place down all through boarding and taxiing. Thought this flight was going to be ghastly, but not a peep out of the little one throught the whole flight. Ban the parents who REFUSE to control their offspring!!!
