This is ridiculous. Being a woman, I understand that the media presents standards of femininity that are impossible for anyone without a team of personal trainers and stylists to achieve, but royals are not "celebrities" in the traditional sense. They can't present themselves to the world as being "just like us" because then what would be the point of royalty as an institution? Royals have to set themselves apart if they're going to continue being royals.
I also don't think it's fair to ask Meghan to skip the photo op because I don't know that she and Harry actually have the option of doing that, both because of the sheer amount of interest in the baby (I mean, if they skip the outside the hospital photo, then photographers are just going to be camped out in Windsor until they can get a photo of the baby, which won't be very peaceful for the Sussexes), and because of the optics involved. Someone on another board brought up an interesting point about whether the baby will be styled Prince/ss by arguing that regardless of whether Harry and Meghan want their baby to have a title, the Queen is very aware of how it would look if the family's first biracial member isn't given a title that was granted to William's kids and Andrew's kids (even though the circumstances are different, Harry being neither the son of a monarch nor the heir to the heir, and even though Edward's kids aren't styled as Prince and Princess). I'd never considered that, but I think that's a good point. People would make something out of it, even though there would be perfectly reasonable explanations from both a protocol standpoint (Harry's kids aren't automatically entitled) and a preference standpoint (Harry and Meghan might not want their kids to have titles). I think it would be the same with the photo op. Even though there might be good reasons not to, some people would perceive not doing it as the royal family "hiding" the Sussex baby.
