Have you every had to deal with spoiled kids?
I've was a nanny for several years at one point. Generally speaking, parents realized they needed to make a change when they saw how someone else interacted with their child and how positive saying no and setting boundaries could be.
I cared for many lovely, kind families who simply wanted the best for their children and don't really know how to say no. They want their children to have everything they don't/didn't so they just lavish on appeasement
