On a packed commuter train this morning was an incredibly noisy toddler (he must have been around 3 – 3 and a half or so). As I got on the train he was raging, mid-tantrum, wailing that he wanted a particular seat on the train, and that he wanted the train to be going the other way to the direction it was actually travelling in. This was actually quite funny, if annoying, and went on for about 10 minutes. His mother was very nice and calm, didn’t really do or say much but eventually he stopped with his tantrum. However, for the rest of the journey, he was talking in what I can only think was the very top of his voice, narrating the things he saw, just general toddler chat I suppose (it was quite sweet really). His mother was sort of engaging with him in a nice way. But my genuine question is whether parents should try and help toddlers to moderate their speaking volume sometimes, or is this just a ridiculous / unreasonable thought / an absolute fantasy? For context, it was a rush hour train, most people looked like they might have been trying to read newspapers / check work emails etc. Everyone has an equal right to be on any train they like but I just wonder whether one should expect a bit more peace and quiet in rush hour? Or am I mad to think that you can ever expect to moderate or control how a toddler speaks or indeed the volume of it? Currently expecting my first child and I have no idea how I would personally approach this, but I am conscious that I found the toddler this morning incredibly irritating and distracting. AIBU?
