American chiming in here:
I initially assumed it was surrogacy, too, based on the bed. If they had an existing relationship with a surrogate, and she was comfortable with their presence, then it would make sense for them to be in her room. It's believable that she'd be ok with them using her room and even her bed for a photo shoot. But if they adopted the children of someone they'd never met, then obviously they wouldn't be in her room using her bed as a prop. So it must have been an empty room, which raises other questions.
The American media talks incessantly about covid-related hospital bed shortages. I understand that the beds themselves aren't literally what they're running out of (though you see occasional stories about patients lying on floors). I don't know which hospital this was or whether that area has a shortage currently. But neither do most people who just look at the picture, so an unknown hospital letting non-patients use an empty room and bed for a photo op is obviously going to raise eyebrows.
I've never heard of someone booking a hospital room as though it were a hotel, and even if that were allowed ordinarily, I guarantee it wouldn't be for normal people during covid. Pediatric rooms usually have some kind of furniture parents can sleep on, like a sofa or recliner or futon, but generally not an extra hospital bed.
Also, the waiting list for adopting a surrendered newborns in the US is a lot longer than a few months, so either they've been on it for years and it just now became public, or they used their connections to jump the line.
