Surely most children can do both. My two are well behaved in public 90% of the time, we've been to plenty of restaurants/musicals/museums etc where they have been perfectly polite and well behaved. I've also had to abandon the trolly mid shop and drag them out because of noise, running and arguing!
This!
I'm inclined to think it's a mixture for all DC. I'm a pretty strict parent, and took my DC lots of places when they were little (single parent) and I expected good behaviour, and generally got it.
However, they can be nightmares too, yes, more likely at home but they fight, shout, misbehave etc.
I am perpetually reminding them to keep it down before we open our front door as they fall out the door, shouting, sometimes fighting & nobody else on our road tends to do this.
I think that 6yo sounds great.
I also feel that every normal child has their moments - mine can be great, they can be demons. I do really place an emphasis on manners in public places. However my most upsetting day as a parent was in a coffee shop when I had shushed them quite a few times, given out a bit to one of them for continually asking for something they weren't going to get, and an older lady at the next table stopped on her way out & said, 'it's really very unpleasant to listening to you. They are good children', and when I said 'Sorry?', in utter shock, she repeated it, making it clear she felt I was overdoing it, and was actually being irritating to her, having to listen to me chastise the kids.
Maybe she had a point, I may have been too 'shh', 'stop' but was always so paranoid about the kids acting up.
She left but I burst into tears. I got through the rest of our time there but just cried & cried after. It really hit a nerve. I felt like wailing, 'I'm doing my best!'
(The DC were great actually, and stoutly defended me, not to her, just to me!)
Long-winded but my point is that there's a lot of swings & roundabouts. Most kids are a mix of good & not-so-good behaviour, if just comes out at different times!
