I tend to agree.
This is the biggest role of her life. Yes, expectant mothers are protective of their bump, and that's fine but she is a ROYAL pregnant duchess, and maybe she is not aware of the sort of dignified way in which the royal family are expected to behave.
Kate has been pregnant three times and never drew attention to her state. She didn't wear clingy clothes and she certainly didn't cradle her stomach at every opportunity. Most mothers to be don't when out in public. Glossy magazines may magnify the bump, delight in the bump and depict those carrying babies as special earth mothers, but really, this woman is old enough to appreciate this is not the Meghan show. She may be delighted to be pregnant but it is a personal thing.
At home with Harry, no worries, delight in the bump all the time, but this is not an acting gig. She doesn't need to publicise her state at every public opportunity. She strikes me as an attention-seeking diva I am afraid. I can imagine disapproval in royal circles. It's all a tad trashy, imo.
