and want to fit in and that even where there is a background of indulgent parenting, a disruptive child who appears unwilling to partake in every day activities, especially at nursery school and primary school and is "disruptive" or "aggressive" is far more likely to have some kind of SN rather than the default position of "spoiled brat" so often to be found both here on MN and in RL?
I see it repeatedly on threads, people getting irritated because other posters suggest that SN may be a factor. "NO some kids are just brats!" Maybe so but I have yet to come across a really badly behaved child where there wasn't something else going on behind the scenes, whether that be SN or really neglectful and poor parenting.
Of course all bets are off when they hit secondary school age and develop minds of their own
