I wonder if the hospital examined the mum post birth? Maybe they figured it was unnecessary given how many days postpartum she was.
I'm surprised by the swimsuit photos of her with the newborn. I guess the baby is strategically placed to cover a residual bump and she can't have ever been that large to be allowed on a flight at 35 weeks with a one way ticket. I'm also surprised she felt comfortable wearing a swimsuit - personally with lochia I'd have wanted something more covering ( and more layers).
As I'm hinting the photos make me wonder if she really was the mum, but I can't see how it makes sense if she isn't!
