Well IIRC the announcement said summer I think...but she's showing quite a bit so I'm thinking end of May or in June.
As discussed a few times in the thread, no due date was ever announced. The summer was the Daily fail assuming she announced at 3 months. Ignoring they waited till 4 months last pregnancy (and miscarried after).
If May, I am thinking early to mid May at the latest. She doesn't look more then a month behind Kate at best. And that would be right along the time line, waiting past four months like last pregnancy, to announce.
More original in the context of the BRF, yes, but Mia was the tenth most popular girl name in 2016 and has been in the top ten for the last few years. So not at all original in that sense. It's what I would call a "faddy" name which will date.
They will probably choose another currently popular name but not necessarily a "classic" name. Similar names that are in fashion are Ava, Freya, Evie and Isla (which is out because already given to her cousin).
Just because a name is popular now doesn't make it 'faddy' or not classic. Classic names are becoming extremely popular, even very old fashioned names, in the past few years. Seems to be a reaction to balance out all the Aiden, jaden, Raiden, Maden, Braden names that took over.
Top ten in UK: Olivia, Sophie, Amelia, Lily, Emily. Eva, Isabella and Isabelle, and Isla and Mia. Most of those are very classic traditional names (several of them with royal history). The only slightly faddy would be Isla. Add in names like Ella, Poppy, Grace, Charlotte, Sophie and Evelyn in the top 20 and its even more evident. Same with boys where you see Oliver, Jack, George, Noah, Leo, Oscar, Charlie, William, Joshua, Lucas all very traditional names among the top 20.
And when it comes to royal babies- choosing something without any royal pedigree, popular or not, is new and unexpected. Its not predictable like George and Charlotte.
