I think that’s a bit black and white and there’s a danger of criticising people’s parenting here which I think is wrong and not what this thread is for.
I give my boy a smack on the bum when I feel he deserves it but I’m reluctant to justify it on here.
Like Mrs S. I feel I could take my 4 year old pretty much anywhere and not worry about his behaviour, I feel the way my wife and I have disciplined him has contributed to that.
Each to their own though.
