My nearly two year old and I were travelling home on the train from my SILs (visiting new baby).. We stayed longer than intended so he missed his nap and was restless on the train. I had him on my lap, looking at a toddler game which makes a twinkling sound when he touches the screen (along with colours and shapes).. The "conductor" (was the London Overground - it said conductor on his jacket, he seemed to be getting off at each stop and blowing a whistle!) told me to turn the sound off as it was disturbing others in the carriage - I hadnt noticed anyone looking disturbed by it, nor disturbed by a woman who kept shouting down her phone whenever it rang..
I did as I was told - turned the sound off - but my tired and grumpy boy had a meltdown and cried on my lap for the next few stops, and only stopped when I let him get down and wandered the carriage with him..
Surely the twinking mobile noise would have been better than a screaming child?!!!
