I get what you are saying, IKEA!
When we are children we don't have the maturity to consider the impact of our behaviours on others, I mean not to any great length that would prevent a child talking to much in class or being cheeky to a teacher or challenging the rules etc.
I was a troublesome pupil in school but I was a very nice kid, honestly!!! Actually, I believe it was a small number of very poor primary school teachers who made me feel very worthless (I wasn't the brightest) and this was actually the route of why I misbehaved.
As a child I had a real problem with authority and challenged it all the time but like I said this was because a few teachers had misused their authority - still struggle in some situations in my adult life to be rule abiding (small things) which is why I decided to leave the teaching profession to find a more suitable career.......it was clear to me that I trained as a teacher to put a few wrongs to right from my own school life but unfortunately I just found some of the pettiness to hard to take e.g having to enforce things like the uniform and PE kit policy, wrong socks, lost tie - I mean, WHO CARES!! Detentions for small minor things, and the hierarchy of the teachers and all the associated bollocks - from my experience, the women were the worst - sorry thats a bit irrelevant!
I just didn't care enough about the small stuff and summarised that for me to continue teaching was like forcing a square peg in a round hole!
As a kid and also looking back, I feel lucky to have a very supportive mum - I watched her regularly challenge the teachers who bullied me, she would rightfully demand apologies, stormed into my classroom once mid lesson and dragged my horror of a teacher to one side and firmly put the witch in her place - I have no doubt that my mum was also the reason I challenged authority figures if I felt "wronged" even as I got a bit older, but as a child it can take a while to work out when you should do this and when you shouldn't - that comes with maturity so it's fair to say that I wasn't always right when I did this and no doubt at times I was just a pain in the arse to teach!
My mum however was just happy knowing that she was teaching me to stand up for myself - as far as she was concerned the rest would work itself out!
When I think of my DD, I've mentioned before that by nature she is very rule abiding and her personality lends to wanting to conform.
Unlike me when I was her age, she is a confident kid and enjoys learning but we do not all find school this rewarding!!!
As a child I would have struggled immensely in my DD's current school, fingers on mouths in assembly, virtual silence in lessons, the head told me they don't have a single behaviour problem in the entire school 🙄, the school is incredibly inflexible - which is why my son lasted 8 days before being promptly removed!
My son is far from naughty, he's sweet, kind but at this point and certainly when he was 5, he will push a few boundaries, bit chatty, less focussed. He currently gets his kicks and confidence playing his sports and school is just something he has to do......clearly a very different mindset, not wrong, just different!
All these things have contributed to asking for peoples thoughts on this situation, clearly there is no right or wrong answer!
I suppose I just resonant a little with these so called naughty kids, I was one of those kids, but genuinely I had a heart of gold and was a great friend, so I do find myself shrugging my shoulders a bit at the thought of a bit of disruptive behaviour in my daughters class.......but then again, my DD is not me and has had a very different upbringing to mine, so why have this issue in her classroom if you don't necessarily need to?? Also very importantly, unlike you IKEA who obviously managed a good balance, I didn't achieve my potential so this weighs heavily on my mind!
oh dear - back to square one! 
Thanks again for everybody's input x
