How about 2?
The way her birth was handled. I think exactly the same result for their family could have been achieved with much less negative publicity if the media had been handled better. The patronising initial statement about privacy, the shambles on the day, the eye to American timings etc all played badly.
I also think her baby shower was a misstep. Of course she can have a baby shower but the private jets, expensive hotel, Hollywood guests being papped arriving holding huge gifts, insta stories etc etc, has I think in part shaped the way she has been perceived by the public.
There are plenty of others - her comments at the Lion King premiere, the way her deteriorating relationship with her father has been played out in the press, having her friends give comments to the media and so on.
