"Why? Because egg viability, egg health and the ability to carry to term were all concerns."Just reading the Blind Gossip about the IVF.
Although it mentions that Archie and Nextbaby carry the Markles' genetic inheritance, there's a big omission as to whether the babies were/are carried by M herself.
Is Markle's weird insistence that the babies get Prince/Princess titles reflecting a belief that it would be a way of enforcing a place in the line of succession, in case the truth comes out that Archie and Nextbaby were not 'born of the body'?
It is an odd statement to put in without explanation.
