I am a FA with BA and also have two kids (5and3) A lot of the crew on BA are, if I may say, slightly older and have kids themselves so understand the "fun" of travelling with little ones!!!!!!
As far as the comment about the sleeping child goes... Whilst I would never in a million and more years condone those comments, as FA we encounter some incredibly badly behaved kids. Some parents allow their kids to play in the galley during the meal service. I ask myself... would they allow their child to play in the kitchen of a restaurant? With the hot food and liquids around? This crew member had probably encountered this scenario a thousand times. But, it still doesn't excuse thier attitude! Having said that. Well behaved kids are very welcome on all of my flts. As are well behaved adults!!!!!!!
