I think Harry and Meghan have managed it well.
I think it's the hypocrisy that annoys people @simpsonthecat. Harry is on record (in his most recent podcast interview with Hasan Minhaj) telling parents they shouldn't be putting photos of their children online, while the Sussexes the same week released photos and videos of their pumpkin patch trip.
The Wales children (at least George, and most likely the other two) will have a constitutional role as working royals, so need to get used to public appearances. Their parents are clearly trying to manage this. The Sussex children do not have that role.
