Happy new year!
I can't see M & H doing the steps thing, though I could be wrong. However:
A. They are in a different position to W & K
B. The press won't exactly have endeared themselves with their recent stories, so why should they parade for them?
C. The DM etc would use it against Megan (no doubt they will do the same if she doesn't but at least she'll be in comfortable shoes).
D. Megan is a feminist, and I don't think that the steps parade is particularly female friendly... I don't blame W & K for feeling they have to but it's not a female-friendly thing to do, the poor woman.
I hope to god they eschew the steps ridiculousness and perhaps release a nice picture which has been taken at their leisure and convenience. Maybe even two! But ones taken when they're ready. And that they'll be left alone to bond and get over the birth and all that, which is the least any new parents should be able to do.
