Whether 5 pics or 3, whether taken at 9:45am or earlier or later - I would like to know, why it was so important this special day, to have x photos of little WT, although he has a sister, who is (on 1 pic) sitting nearby, but holding her head down. They are bio siblings close in their age, why only take a photograph of one of them? If the pic was taken for his "foster book", it wouldn't also make sense at all, because they are real siblings. The F parent tried to adopt both of the children, that would even make less sense then in taking only pics of him (in terms of the future of the bio siblings).
That "last" photo seems to be so very meaningful to me, as if nobody else should have been shown with the pic. Neither the FGM nor the little sister in the background, head down, unrecognizable. As if a photo got prepared, which would be needed to search for him later on. Sweet little boy, red spider man suit.
All IMO and MOO
Maybe it doesn't mean anything indeed, but it won't disappear from my mind.
