I’ve been fighting a temper I thought I long since had handle on since having my twins and they’re only just 2yo - DD is extremely cheeky and amazing but sometimes her sense of humour, such as pouring her breakfast all over me as she did 15 minutes ago and then complaining that she is hungry now, makes me internally scream, but I wouldn’t shout in the way you have described @backdoormadness
I think a lot of posters have become defensive, because I can’t think of any parent I’ve met that hasn’t lost their self control sometimes and snapped, which can come across as ‘shouting’ by what I understand, as in a raised voice/harsh tone but usually not drawn out in a tirade, just a loud statement of what needs to be done and I see no issue with this, my Grandparents did the same and worse when I was a child.
But I think the shouting you’re referring to (and correct me if I’m wrong) usually includes some real contempt for the child and it makes me sad too. There’s a difference to, let’s say, my neighbours shouting at their son at the top of their lungs when the boy is about to cycle out of the cul de sac onto the main road (mostly shouting so he hears them, he’s young and knows not to go that far but he’s at an age where he pushes his luck a lot!) - and a parent that will corner and verbally bully a small child.
But it’s all shades of grey, you only know what you glean based on the small window you get into another’s life, but equally, it doesn’t have to sit well with those who witness it.
This week I had to lift my DS who has speech delay and carry him superman style out of the toddler play group whilst my Mum sat in to keep an eye on my DD. He was having an almighty meltdown and pushed another toddler over - he is struggling with socialising - when I saw it I used my ‘mum voice’ to stop him in his tracks and then he got upset so I had to carry him away to a quiet place. In doing so I could comfort him whilst trying to get through to him (age appropriately) why it was wrong that he’d lashed out at another child.
I’m sure no end of people would have caught a glimpse of various parts of this small event as the play group is in a busy leisure centre, but none would have seen the entirety. Depending on which bit they saw they might judge me differently, depending on their own life experience they might see aggression where there is none, so with others I generally lean towards trying not to judge.
