Being a part of any royal family can be a harrowing experience but that doesn't have to be the case for every one of them which is certainly something that Harry and Meghan would rather have for their child.
Living under the radar might be a bit difficult for celebrities, and all the more so for the British royal family but that doesn't mean it can't be done. Certainly, several royals have already lived as private citizens, away from the media and paparazzi.
Some other royals have lived as non-royals or those who aren't working royals and won't have the duties that those in the main line of succession need to carry.
It's definitely something that we would all want, to have our privacy within our control and to be away from public scrutiny. A child born into the royal family need not bear the same fate of fame and being under the public eye.
